    DANNY DOUGAN v. SIKORSKY AIRCRAFT
    CORPORATION ET AL.
    (SC 20271)
    Robinson, C. J., and Palmer, McDonald, D’Auria,
    Mullins, Kahn and Ecker, Js.*
    Syllabus
    The plaintiffs sought to recover damages from the defendants, S Co. and
    its general contractor, C Co., alleging, inter alia, that they had been
    negligently exposed to asbestos while working for subcontractors on a
    construction project at S Co.’s facility. Specifically, the plaintiffs sought
    compensatory and punitive damages, the costs of medical monitoring
    for asbestos related diseases, and the establishment of a court monitored
    fund to pay those costs. The defendants moved for summary judgment
    on the ground that the plaintiffs had not suffered any actual injuries
    and, instead, were seeking medical monitoring for the risk of future
    injuries, which the defendants claimed is not cognizable under Connecti-
    cut law. The trial court determined that, because the plaintiffs conceded
    that they had not been diagnosed with an asbestos related disease, they
    had failed to establish a genuine issue of material fact as to the existence
    of a physical injury. Addressing an issue of first impression under Con-
    necticut law, the court then concluded that a claim for medical monitor-
    ing for an increased risk of future injury, in the absence of any present,
    physical harm, was not cognizable under Connecticut law. Thereafter,
    the court granted the defendants’ motion for summary judgment and
    rendered judgment for the defendants. On the plaintiffs’ appeal, held
    that the trial court’s judgment was affirmed on the alternative ground
    that, even if this court were to recognize a cause of action for medical
    monitoring in the absence of the present manifestation of physical injury,
    the plaintiffs nevertheless failed to establish a genuine issue of material
    fact as to other elements of a medical monitoring claim, namely, whether
    medical monitoring was reasonably necessary for each individual plain-
    tiff.

    Procedural History
    Action to recover damages for, inter alia, the defen-
    dants’ alleged negligence in exposing the named plain-
    tiff to asbestos, and for other relief, brought to the
    Superior Court in the judicial district of Tolland and
    transferred to the judicial district of Hartford, Complex
    Litigation Docket, where Philip Badorek et al. were
    added as plaintiffs; thereafter, the court, Miller, J.,
    granted in part the motion of the named defendant et
    al. to strike and granted in part the plaintiffs’ motion
    for class certification; subsequently, the court, Moll, J.,
    granted the motions of the named defendant et al. for
    summary judgment, vacated the order granting class
    certification, and rendered judgment for the named
    defendant et al., from which the plaintiffs appealed.

    Opinion
    ROBINSON, C. J. This appeal requires us to consider
    the proof necessary to establish a claim for medical
    monitoring, the availability of which is a question of
    first impression under Connecticut law. The plaintiffs
    Philip Badorek, Michael Daley, William Grem IV, and
    Fred Ferrara1 appeal from the judgment of the trial court
    rendered in favor of the defendants Sikorsky Aircraft
    Corporation (Sikorsky) and Carrier Corporation (Carrier)2
    on their medical monitoring claims, which stemmed
    from a workplace asbestos exposure at Sikorsky’s cogen-
    eration project in Stratford. On appeal,3 the plaintiffs
    claim that the trial court improperly granted the defen-
    dants’ motion for summary judgment because (1) a
    genuine issue of material fact exists with respect to
    the issue of physical injury because the plaintiffs each
    currently suffer from a subclinical injury as a result of
    asbestos exposure, and (2) Connecticut law permits a
    cause of action4 for medical monitoring. We conclude
    that the trial court properly granted the defendants’
    motion for summary judgment, albeit on alternative
    grounds, because, even if we were to recognize a medi-
    cal monitoring claim in the absence of any physical
    manifestation of injury under Connecticut law, the
    plaintiffs nevertheless failed to establish a genuine issue
    of material fact as to certain elements of the claim, in
    particular, whether the provision of medical monitoring
    is reasonably necessary for them. Accordingly, we
    affirm the judgment of the trial court.
    The record reveals the following undisputed relevant
    facts and procedural history. In September, 2009, Sikor-
    sky began work on a cogeneration project at its manu-
    facturing facilities in Stratford. Sikorsky hired Carrier
    as the general contractor responsible for the project,
    which involved building a new cogeneration plant and
    renovating Sikorsky’s existing boiler house. Three of the
    plaintiffs, Badorek, Daley, and Grem, were employed
    by B-G Mechanical Contractors, Inc. (B-G Mechanical),
    one of Carrier’s subcontractors on the cogeneration
    project. B-G Mechanical employees were responsible
    for removing pipe from Sikorsky’s boiler house. As a
    result, these plaintiffs were present at various times at
    the site from March, 2010, to July, 2010. The fourth
    plaintiff, Ferrara, was employed by Tucker Mechanical,
    Inc., another subcontractor, and was present on site
    for a period of time in March, 2010.5
    At some point during the project, some workers
    began to complain of sore throats. Then, on July 7 or
    8, 2010, a B-G Mechanical employee discovered what
    he believed to be asbestos present in the boiler house.
    Sikorsky then performed testing that confirmed the
    presence of asbestos in the boiler house and in an
    exterior dumpster. As a result, Sikorsky halted the proj-
    ect on or about July 23, 2010, in order to remediate the
    asbestos. The plaintiffs asserted in their complaint that
    Sikorsky was aware of the presence of asbestos in the
    boiler house before work on the project began. In
    response, Sikorsky admitted that, after performing sur-
    veys in 2001 and 2008, asbestos had been discovered
    in a small amount of pipe insulation in the boiler house
    basement but averred that the Sikorsky employees in
    charge of the cogeneration project were unaware of
    this fact.
    The named plaintiff, Danny Dougan; see footnote 1
    of this opinion; brought a class action complaint in May,
    2012, against Sikorsky, Carrier, and URS Corporation
    AES (URS).6 The operative complaint, filed on April 1,
    2013, includes claims of negligence, battery, reckless-
    ness, and strict liability for violations of the federal
    Clean Air Act, 
    42 U.S.C. § 7401
     et seq., on behalf of
    Dougan, Grem, Daley, Badorek, and Ferrara individu-
    ally, as well as ‘‘all others similarly situated who were
    exposed to asbestos while working at the [Sikorsky
    cogeneration project in Stratford] from the period of
    approximately March, 2010, to mid-July, 2010, and who
    are now seeking to pursue remedies for said exposure.’’
    The plaintiffs sought compensatory damages, punitive
    damages, the costs of medical monitoring, and the
    establishment of a ‘‘court monitored fund’’ for the pay-
    ment of medical monitoring of asbestos related dis-
    eases.7
    In March, 2016, Carrier and Sikorsky moved for sum-
    mary judgment on all counts of the plaintiffs’ com-
    plaint.8 The defendants contended that the plaintiffs
    had not suffered actual injuries and, instead, sought
    medical monitoring for a risk of future injury, which
    they claimed is not a cognizable claim under Connecti-
    cut law. Specifically, they argued that (1) the court
    should not recognize a remedy for medical monitoring
    based on exposure alone, (2) even under the plaintiffs’
    theory of recovery, summary judgment is appropriate
    because Dougan could not prove that his need for medi-
    cal monitoring resulted from asbestos exposure, and
    because the other four plaintiffs failed to produce any
    expert testimony demonstrating their need for medical
    monitoring, and (3) certain claims failed as a matter of
    law, specifically, the plaintiffs’ claims for battery, strict
    liability, and punitive damages. The defendants filed
    numerous exhibits in support of their motion, including
    excerpts of deposition transcripts of the plaintiffs’ two
    medical experts, M. Saud Anwar and Oyebode Taiwo,
    and the defendants’ medical expert, Barry W. Levine.
    Levine’s deposition testimony discussed his examina-
    tion of Dougan and the general effects of asbestos expo-
    sure, including the long latency period before asbestos
    related diseases manifest. In their depositions, both
    Anwar and Taiwo stated that they had not formed any
    opinions regarding the claims of Grem, Badorek, Daly,
    or Ferrara. Additionally, Anwar acknowledged that ‘‘a
    significant percentage of people who are exposed to
    and inhale asbestos . . . never develop clinical symp-
    toms . . . .’’
    The plaintiffs filed an objection to the summary judg-
    ment motion, contesting the defendants’ characteriza-
    tion of their knowledge of the presence of asbestos,
    the current status of the law of medical monitoring,
    and the public policy reasons against extending liability.
    Along with their objection, the plaintiffs included an
    affidavit from Anwar. Anwar’s three page affidavit spe-
    cifically addressed his treatment of Dougan and con-
    cluded that Dougan suffered from a ‘‘significantly
    increased risk of contracting a serious disease,’’ and
    also discussed generally the risks of asbestos, such as
    the injuries asbestos fibers cause to a person’s lungs
    when inhaled. Additionally, the affidavit stated that
    ‘‘[o]ther individuals who were exposed to asbestos dur-
    ing the demolition work at Sikorsky should be moni-
    tored for the early detection and intervention of an
    asbestos related disease . . . .’’ The plaintiffs also sub-
    mitted other exhibits concerning the presence of asbes-
    tos at Sikorsky and the defendants’ actions surrounding
    the incident, but they provided no further expert testi-
    mony.
    On March 28, 2017, the trial court granted the defen-
    dants’ motion for summary judgment. See footnote 8
    of this opinion. In its memorandum of decision, the
    trial court reviewed the evidence in the record and
    determined that no expert had examined or reviewed
    the medical records of any of the plaintiffs other than
    Dougan and that all of the plaintiffs admitted that they
    had not been diagnosed with an asbestos related dis-
    ease, specifically, ‘‘mesothelioma, lung cancer, asbesto-
    sis, or pleural effusions.’’ As a result, the trial court
    determined that the plaintiffs had not presented evi-
    dence demonstrating a genuine issue of material fact
    as to physical injury. The trial court then applied the
    public policy test outlined in Lawrence v. O & G Indus-
    tries, Inc., 
    319 Conn. 641
    , 650–51, 
    126 A.3d 569
     (2015),
    and declined to recognize a cause of action for medical
    monitoring under Connecticut law that would allow
    recovery for an increased risk of future injury rather
    than a present injury. Accordingly, the court granted
    the defendants’ motion for summary judgment, vacated
    the class certification order, and rendered judgment for
    the defendants on the remaining counts. See footnotes
    7 and 8 of this opinion. The trial court later denied the
    plaintiffs’ motion for reargument or reconsideration.
    This appeal followed. See footnotes 1 and 3 of this
    opinion.
    On appeal, the plaintiffs argue that the trial court
    incorrectly concluded that medical monitoring claims
    in the absence of clinical symptoms should not be per-
    mitted under Connecticut tort law. The plaintiffs further
    argue that the trial court incorrectly determined that
    there was no genuine dispute of material fact as to their
    injuries because they suffer from subclinical injuries as
    a result of their asbestos exposure. In response, the
    defendants counter that the trial court properly declined
    to create a medical monitoring remedy for asymptomatic
    plaintiffs exposed to toxic substances in the absence
    of physical harm. As an alternative ground for affirming
    the judgment of the trial court, the defendants argue
    that, even if this court were to recognize medical moni-
    toring as a cause of action, the plaintiffs’ claims would
    still fail because they are not supported by ‘‘reliable,
    scientific evidence . . . .’’9 We agree with the defen-
    dants that, even if we were to recognize a remedy in
    Connecticut for medical monitoring in the absence of
    the present manifestation of physical harm, the plain-
    tiffs’ claims would still fail as a matter of law because
    the plaintiffs failed to prove that monitoring was medi-
    cally necessary.
    We first set forth the applicable standard of review.
    ‘‘Practice Book [§ 17-49] provides that summary judg-
    ment shall be rendered forthwith if the pleadings, affida-
    vits and any other proof submitted show that there is
    no genuine issue as to any material fact and that the
    moving party is entitled to judgment as a matter of law.
    . . . In deciding a motion for summary judgment, the
    trial court must view the evidence in the light most
    favorable to the nonmoving party. . . . The party seek-
    ing summary judgment has the burden of showing the
    absence of any genuine issue [of] material facts which,
    under applicable principles of substantive law, entitle
    him to a judgment as a matter of law . . . and the party
    opposing such a motion must provide an evidentiary
    foundation to demonstrate the existence of a genuine
    issue of material fact. . . . A material fact . . . [is] a
    fact which will make a difference in the result of the
    case. . . . Finally, the scope of our review of the trial
    court’s decision to grant the plaintiff’s motion for sum-
    mary judgment is plenary.’’ (Internal quotation marks

    316 Conn. 809
    , 820–21, 
    116 A.3d 1195
     (2015).
    ‘‘When documents submitted in support of a motion
    for summary judgment fail to establish that there is no
    genuine issue of material fact, the nonmoving party
    has no obligation to submit documents establishing the
    existence of such an issue. . . . Once the moving party
    has met its burden, however, the opposing party must
    present evidence that demonstrates the existence of
    some disputed factual issue. . . . It is not enough, how-
    ever, for the opposing party merely to assert the exis-
    tence of such a disputed issue. Mere assertions of fact
    . . . are insufficient to establish the existence of a
    material fact and, therefore, cannot refute evidence
    properly presented to the court under Practice Book
    [§ 17-45] . . . .’’ (Internal quotation marks omitted.)

    I
    We begin our analysis with a review of the medical
    monitoring claim. Medical monitoring, either in the
    form of damages or as a stand-alone cause of action;
    see footnote 4 of this opinion; allows a plaintiff to
    recover the cost of diagnostic testing for an injury that
    may occur in the future as a result of a defendant’s
    tortious conduct.10 See, e.g., Metro-North Commuter
    Railroad Co. v. Buckley, 
    521 U.S. 424
    , 438, 
    117 S. Ct. 2113
    , 
    138 L. Ed. 2d 560
     (1997) (defining medical moni-
    toring as ‘‘the economic cost of the extra medical check-
    ups that [the plaintiff] expects to incur as a result of
    his exposure to [toxins]’’). Given the nature of the relief
    provided by medical monitoring and the prevalence of
    these claims in the world of toxic torts,11 the central
    issue in such cases is whether to permit medical moni-
    toring in the absence of some present manifestation of
    a physical injury. Although medical monitoring is no
    longer a novel theory of recovery in many states,
    whether such recovery is permitted in Connecticut is
    still an open question of law. See Doe v. Stamford, 
    241 Conn. 692
    , 699–700 n.8, 
    699 A.2d 52
     (1997) (discussing

     (1991),
    but noting that neither party requested its adoption in
    workers’ compensation law); see also McCullough v.
    World Wrestling Entertainment, Inc., 
    172 F. Supp. 3d 528
    , 567 (D. Conn. 2016) (discussing how ‘‘[f]ew Con-
    necticut courts’’ have considered viability of stand-
    alone medical monitoring claims), aff’d in part and
    appeal dismissed in part sub nom. Haynes v. World
    Wrestling Entertainment, Inc., 
    827 Fed. Appx. 3
     (2d
    Cir. 2020). Given that medical monitoring claims pres-
    ent an issue of first impression in Connecticut, we begin
    with a detailed review of the federal and sister state
    precedents considering these claims.
    In the 1980s and 1990s, state and federal courts began
    permitting medical monitoring recovery in toxic expo-
    sure cases in the absence of a manifestation of present
    physical injury, as in the seminal case of Ayers v. Jack-
    son, 
    106 N.J. 557
    , 604–606, 
    525 A.2d 287
     (1987). See,
    e.g., In re Paoli Railroad Yard PCB Litigation, 
    supra,
    916 F.2d 850
    –52; Burns v. Jaquays Mining Corp., 
    156 Ariz. 375
    , 380, 
    752 P.2d 28
     (App. 1987), review dismissed,
    
    162 Ariz. 186
    , 
    781 P.2d 1373
     (1989); Potter v. Firestone
    Tire & Rubber Co., 
    6 Cal. 4th 965
    , 1007–1009, 
    863 P.2d 795
    , 
    25 Cal. Rptr. 2d 550
     (1993); Hansen v. Mountain
    Fuel Supply Co., 
    858 P.2d 970
    , 977–78 (Utah 1993).
    These cases were often supported by the reasoning
    of an earlier medical monitoring case, Friends for All
    Children, Inc. v. Lockheed Aircraft Corp., 
    746 F.2d 816
    ,
    819, 822, 838 (D.C. Cir. 1984), in which the United States
    Court of Appeals for the District of Columbia Circuit
    upheld the creation of a medical monitoring fund for
    children who suffered from a ‘‘neurological develop-
    ment disorder’’ after a plane crash.12
    Subsequently, in 1997, the United States Supreme
    Court rejected a medical monitoring cause of action
    under federal law in Metro-North Commuter Railroad
    Co. v. Buckley, 
    supra,
     
    521 U.S. 444
    . In that case, an
    asymptomatic plaintiff requested lump sum damages
    under the Federal Employers’ Liability Act, 
    45 U.S.C. § 51
     et seq., after he was exposed to asbestos during
    his duties as a railroad employee. 
    Id.,
     426–27. The court
    considered earlier cases that permitted asymptomatic
    medical monitoring recovery under state law and noted
    that those cases imposed certain ‘‘integral’’ restrictions
    on a plaintiff’s case, such as limiting recovery through
    the establishment of a court administered fund. 
    Id.,
    440–41, 444. The court then outlined several policy con-
    siderations that weighed against the recognition of this
    claim, namely, the substantial number of potential plain-
    tiffs who have been exposed to toxic substances, along
    with the high costs of monitoring. 
    Id., 442
    . But, in light
    of these conflicting policy concerns and the inadequate
    support in the common law, the court declined to create
    ‘‘a new, full-blown, tort law cause of action’’ under the
    federal statute being considered. 
    Id., 443
    .
    State appellate courts have been divided in the wake
    of Buckley with respect to whether to permit recovery
    for medical monitoring in the absence of the manifesta-
    tion of a physical injury under their states’ respective
    laws.13 See V. Schwartz & C. Silverman, ‘‘The Rise of
    ‘Empty Suit’ Litigation: Where Should Tort Law Draw
    the Line?,’’ 
    80 Brook. L. Rev. 599
    , 620 (2015) (discussing
    how, after Buckley, courts rejected claims for medical
    monitoring, but, recently, ‘‘the pendulum briefly swung
    back toward permitting medical monitoring claims’’);
    H. Zarov et al., ‘‘A Medical Monitoring Claim for Asymp-
    tomatic Plaintiffs: Should Illinois Take the Plunge?,’’ 
    12 DePaul J. Health Care L. 1
    , 2 (2009) (‘‘[M]ost courts
    addressing the issue since Buckley have rejected claims
    for medical monitoring absent physical injury. Never-
    theless, a few courts have issued post-Buckley decisions
    adopting claims for medical monitoring, while other
    courts have continued to implement pre-Buckley deci-
    sions. Thus, although there is a clear trend against the
    recognition of medical monitoring claims, the debate
    is far from over.’’).
    A challenging issue presented by the plaintiffs’ claims
    in this case is determining the nature of the harm, if
    any, caused by their exposure to asbestos. Past plain-
    tiffs have sought medical monitoring for a variety of
    injuries, ranging from toxins present in their blood14 to
    traumatic brain injuries.15 The plaintiffs in the present
    case claim that their asbestos exposure caused them
    to suffer a subclinical injury, which is one that is ‘‘not
    detectable or [that is] producing effects that are not
    detectable by the usual clinical tests . . . .’’ Merriam-
    Webster’s Collegiate Dictionary (11th Ed. 2011) p. 1242;
    accord Webster’s New Complete Medical Dictionary
    (1995) p. 667. Relying on Donovan v. Philip Morris
    USA, Inc., 
    455 Mass. 215
    , 
    914 N.E.2d 891
     (2009), the
    plaintiffs contend specifically that the trial court incor-
    rectly determined that their subclinical injuries were
    not actual injuries because, once they were exposed to
    asbestos at the Sikorsky project, the asbestos fibers
    entered their lungs and damaged their cells, creating a
    ‘‘preclinical stage of disease.’’ They ask us to adopt
    the legal framework from Donovan to govern medical
    monitoring claims arising from subclinical injuries.
    In Donovan, the Supreme Judicial Court of Massa-
    chusetts considered a certified question from a federal
    district court asking whether ‘‘the plaintiffs’ suit for
    medical monitoring, based on subclinical effects of
    exposure to cigarette smoke and increased risk of lung
    cancer, state[d] a cognizable claim and/or permit[ted] a
    remedy under Massachusetts state law . . . .’’ (Internal
    quotation marks omitted.) 
    Id.,
     215–16. The plaintiffs, a
    proposed class of Marlboro cigarette smokers, argued
    that the defendant had ‘‘wrongfully designed, marketed,
    and sold’’ its cigarettes and requested a ‘‘court-super-
    vised program’’ for medical monitoring, specifically, of
    ‘‘low-dose computed tomography . . . scans of the
    chest’’ to screen for lung cancer. 
    Id.,
     216–17. The plain-
    tiffs alleged that, because they had used the defendant’s
    defective products, they suffered ‘‘objectively observ-
    able and identifiable damage to the tissues and struc-
    tures of their lungs’’ and, as a result, are at a ‘‘substan-
    tially increased risk of cancer . . . .’’ 
    Id., 221
    .
    The Massachusetts high court accepted the plaintiffs’
    theory of harm and recognized a stand-alone medical
    monitoring cause of action for the plaintiffs’ subclinical
    injuries under Massachusetts law. 
    Id.,
     226–27. The court
    reasoned that, just as a shaken baby would be able to
    recover expenses for diagnostic testing to determine if
    she had suffered a brain injury, so, too, should the
    plaintiffs, as they ‘‘have produced sufficient proof of
    ‘impact’ . . . to safeguard against false claims: they
    have proffered evidence of physiological changes
    caused by smoking, and they have proffered expert
    medical testimony that, because of these physiological
    changes, they are at a substantially greater risk of can-
    cer due to the negligence of Philip Morris.’’ (Citation
    omitted.) 
    Id.,
     224–25. The court discussed the impor-
    tance of subcellular changes, stating that such ‘‘changes
    may occur which, in themselves, are not symptoms of
    any illness or disease, but are warning signs to a trained
    physician that the patient has developed a condition
    that indicates a substantial increase in risk of con-
    tracting a serious illness or disease and thus the patient
    will require periodic monitoring.’’ 
    Id., 225
    . The court in
    Donovan distinguished the facts of that case from those
    in ‘‘cases that involve exposure to levels of chemicals or
    radiation known to cause cancer, for which immediate
    medical monitoring may be medically necessary although
    no symptoms or subclinical changes have occurred.’’
    (Emphasis omitted.) 
    Id.
     Because the record in Donovan
    presented evidence of subcellular change indicating an
    increased risk of cancer, the plaintiffs had adequately
    demonstrated injury.
    The Massachusetts court outlined the following stan-
    dard for its medical monitoring cause of action, requir-
    ing that ‘‘each plaintiff’’ prove that ‘‘(1) [t]he defendant’s
    negligence (2) caused (3) the plaintiff to become exposed
    to a hazardous substance that produced, at least, subcel-
    lular changes that substantially increased the risk of
    serious disease, illness, or injury (4) for which an effec-
    tive medical test for reliable early detection exists, (5)
    and early detection, combined with prompt and effec-
    tive treatment, will significantly decrease the risk of death
    or the severity of the disease, illness or injury, and (6)
    such diagnostic medical examinations are reasonably
    (and periodically) necessary, conformably with the
    standard of care, and (7) the present value of the reason-
    able cost of such tests and care, as of the date of the
    filing of the complaint.’’ 
    Id., 226
    . In addition, the court
    stated that proof of these elements ‘‘usually will require
    competent expert testimony.’’ 
    Id., 227
    .
    II
    Having reviewed the background law governing medi-
    cal monitoring claims, we now turn to the plaintiffs’
    claims in the present appeal. We begin by setting forth
    several assumptions that underlie our analysis. First,
    we will assume, without deciding, that Connecticut law
    recognizes a claim for subclinical cellular injury that
    substantially increased the plaintiffs’ risk of cancer and
    other asbestos related diseases.16 Second, we also
    assume, without deciding, that the Donovan elements
    govern proof of a medical monitoring claim. Finally,
    we assume that the plaintiffs raised a genuine dispute
    of material fact as to whether they were negligently
    exposed to asbestos during the Sikorsky project. We
    nevertheless conclude that the trial court properly
    granted the defendants’ motion for summary judgment
    because the plaintiffs have not established the existence
    of a genuine issue of material fact as to certain Donovan
    factors.17 See, e.g., Stuart v. Freiberg, supra, 
    316 Conn. 823
     (‘‘a plaintiff may properly be called upon at the
    summary judgment stage to demonstrate that he pos-
    sesses sufficient counterevidence to raise a genuine
    issue of material fact as to any, or even all, of the
    essential elements of his [claim]’’).
    Courts, including the one in Donovan, generally
    require competent expert testimony to prove a medical
    monitoring claim or remedy. See, e.g., Caronia v. Philip
    Morris USA, Inc., 
    715 F.3d 417
    , 448 (2d Cir. 2013) (‘‘[a]ll
    of the [previously discussed] states that recognized a
    medical monitoring cause of action noted that such
    a claim cannot be established without reliable expert
    testimony’’); In re Paoli Railroad Yard PCB Litigation,
    
    supra,
     
    916 F.2d 852
     (requiring competent expert testi-
    mony to establish medical monitoring cause of action);
    Donovan v. Philip Morris USA, Inc., 
    supra,
     
    455 Mass. 227
     (‘‘[p]roof of [the Donovan] elements usually will
    require competent expert testimony’’); Ayers v. Jack-
    son, 
    supra,
     
    106 N.J. 606
     (requiring ‘‘reliable expert testi-
    mony’’ to recover medical surveillance damages); Han-
    sen v. Mountain Fuel Supply Co., supra, 
    858 P.2d 979
    n.10 (‘‘[p]roof of [the Donovan] elements will usually
    require expert testimony’’). As a result, if a plaintiff
    lacks expert testimony to prove a medical monitoring
    claim, summary judgment should be granted. See
    Bozelko v. Papastavros, 
    323 Conn. 275
    , 282, 
    147 A.3d 1023
     (2016) (‘‘[s]ummary judgment in favor of a defen-
    dant is proper when expert testimony is necessary to
    prove an essential element of the plaintiff’s case and
    the plaintiff is unable to produce an expert witness to
    provide such testimony’’).
    The defendants argue that the plaintiffs ‘‘have totally
    failed to provide expert evidence establishing their need
    for medical monitoring as a result of asbestos exposure
    at Sikorsky.’’ The plaintiffs do not dispute that Anwar,
    their expert witness, has not provided any testimony
    as to any of them specifically, but they argue that they
    nevertheless have presented sufficient expert evidence
    to survive summary judgment. According to the plain-
    tiffs, ‘‘the court [in Donovan] did not state that the
    plaintiffs needed to offer expert medical evidence that
    spoke to the plaintiffs’ specific conditions; instead, the
    court accepted general expert evidence that attested
    to the undifferentiated effects that cigarette smoking
    [has] on any smoker, including the plaintiffs.’’ Addition-
    ally, the plaintiffs assert only that ‘‘expert evidence must
    be used to generally inform lay jurors about the scien-
    tific correlation between asbestos exposure and the
    onset of asbestos related diseases.’’ Finally, ‘‘the plain-
    tiffs aver that the experts should not form any opinions
    about the plaintiffs’ exposure and their need for medical
    monitoring or the likelihood of contracting diseases
    because that function should be reserved [for] the trier
    of fact.’’
    We disagree with the plaintiffs that the Donovan
    court’s acceptance of ‘‘general expert advice’’ assists
    this inquiry, as that court was considering whether the
    parties had stated a claim for medical monitoring on a
    motion to dismiss, not whether the plaintiffs’ claims
    could ultimately survive summary judgment. See Dono-
    van v. Philip Morris USA, Inc., 
    supra,
     
    455 Mass. 217
    ,
    221. Accordingly, we will look to the requirements of
    other courts reviewing this issue, including those cited
    with approval in Donovan.
    The third Donovan factor requires a plaintiff to dem-
    onstrate that he or she suffers from a subcellular change
    that substantially increases his or her risk of disease.
    
    Id., 226
    . A Massachusetts federal district court recently
    considered whether expert testimony sufficiently dem-
    onstrated subcellular change on a motion for summary
    judgment. See Genereux v. Hardric Laboratories, Inc.,
    
    950 F. Supp. 2d 329
     (D. Mass. 2013), aff’d, 
    754 F.3d 51
    (1st Cir. 2014). The defendant in Genereux argued that
    the plaintiffs would be unable to succeed at trial under
    Donovan because the plaintiffs’ expert had ‘‘testified
    that he cannot state, with reasonable medical certainty,
    that any plaintiff has suffered subcellular change.’’ 
    Id., 333
    . The plaintiffs’ expert concluded only that ‘‘some
    number of persons will have cellular changes in the
    blood or lung cells’’ and ‘‘did not state that any specific
    plaintiff or plaintiffs have suffered beryllium-related
    subcellular change.’’ (Internal quotation marks omit-
    ted.) 
    Id., 336
    . The court concluded that ‘‘each plaintiff
    must submit sufficient admissible evidence to permit a
    reasonable fact finder to find that he or she has suffered
    subcellular change.’’ (Emphasis added.) 
    Id., 340
    .
    Because the plaintiffs had failed to do so, the court
    rendered summary judgment for the defendant.

    indicia that a defendant’s actions have so increased
    significantly the plaintiff’s risk of developing a disease
    are necessary to recover damages for medical monitor-
    ing costs. The indicia may be proven by a medical
    expert’s testimony, particularized to a plaintiff, and
    demonstrating a reasonable link to toxic exposure.’’

     (2013).18
    The expert affidavit in the present case is ambiguous
    at best about whether each plaintiff actually suffered
    subcellular harm that substantially increased his risk
    of injury.19 Anwar does aver that ‘‘[a]sbestos fibers are
    readily inhaled into the lungs where the fibers cause
    changes at [the] cellular level.’’ But the affidavit does
    not state specifically that Grem, Ferrara, Daley, and
    Badorek have themselves suffered subcellular change
    that substantially increased their risk of serious disease,
    illness, or injury. As a result, it is unclear whether Anwar
    is concluding that all persons necessarily suffer harmful
    subcellular change as soon as they are exposed to asbes-
    tos, as the plaintiffs in Donovan established with
    respect to cigarette smoke after the case returned to
    the federal court or, instead, that one can inhale asbes-
    tos and only possibly suffer subcellular change that
    ‘‘substantially increase[s] the risk of serious disease,
    illness, or injury . . . .’’ Donovan v. Philip Morris USA,
    Inc., 
    supra,
     
    455 Mass. 226
    ; see also Donovan v. Philip
    Morris USA, Inc., 
    268 F.R.D. 1
    , 16 (D. Mass. 2010)
    (‘‘Indeed, subcellular harm, according to [the] plaintiffs,
    begins as soon as someone takes a single puff. . . .
    While the extent of the damage and risk may vary among
    class members, allegedly twenty pack-years of smoking
    necessarily causes subcellular harm. . . . I find their
    expert affidavits and depositions . . . sufficient on this
    point for class certification purposes.’’ (Citations omit-
    ted; emphasis altered; footnote omitted.)). This ambigu-
    ity alone does not defeat summary judgment, however,
    because we construe the evidence in the light most
    favorable to the nonmoving party, and, therefore, we
    will read Anwar’s conclusions about subcellular harm
    as applicable to all of the plaintiffs.
    Nevertheless, we conclude that the plaintiffs have
    failed to present sufficient evidence as to certain other
    factors under Donovan, specifically, that ‘‘early detec-
    tion, combined with prompt and effective treatment,
    will significantly decrease the risk of death or the sever-
    ity of the disease, illness or injury,’’ and that ‘‘such
    diagnostic medical examinations are reasonably (and
    periodically) necessary, conformably with the standard
    of care . . . .’’ Donovan v. Philip Morris USA, Inc.,
    
    supra,
     
    455 Mass. 226
    ; see In re Marine Asbestos Cases,
    
    265 F.3d 861
    , 867–68 (9th Cir. 2001) (upholding sum-
    mary judgment for defendants because plaintiffs did
    not ‘‘present sufficient evidence to raise a genuine issue
    of material fact as to the reasonableness and necessity’’
    of medical monitoring, as plaintiffs ‘‘submitted no evi-
    dence that a single examination would yield any clinical
    benefit,’’ and their expert affidavit ‘‘did not explain how
    patients would benefit from the single, baseline exami-
    nation that [the] plaintiffs seek’’).
    When discussing the expert testimony requirement
    in Donovan, the Massachusetts Supreme Judicial Court
    cited the Utah Supreme Court’s decision in Hansen v.
    Mountain Fuel Supply Co., supra, 
    858 P.2d 970
    . See
    Donovan v. Philip Morris USA, Inc., supra, 
    455 Mass. 227
    . In Hansen, the Utah Supreme Court reversed the
    trial court’s grant of summary judgment on the plain-
    tiffs’ medical monitoring claims and discussed the ele-
    ments that a plaintiff must prove to establish such a
    claim. Hansen v. Mountain Fuel Supply Co., supra, 972,
    979. Although the Donovan elements are not identical
    to those in Hansen, there is significant overlap, and,
    as such, we look to the explanation in Hansen of how
    to prove medical necessity.20
    The court in Hansen stated: ‘‘It also must be shown
    that administration of the [medical] test to a specific
    plaintiff is medically advisable for that plaintiff. To
    illustrate, a monitoring regime might be of theoretical
    value in detecting and treating a particular illness, but
    if a reasonable physician would not prescribe it for a
    particular plaintiff because the benefits of the monitor-
    ing would be outweighed by the costs, which may
    include, among other things, the burdensome frequency
    of the monitoring procedure, its excessive price, or its
    risk of harm to the patient, then recovery would not be
    allowed. . . . We emphasize that the advisable medical
    testing for a specific plaintiff must be shown to be
    ‘consistent with contemporary scientific principles’ and
    ‘reasonably necessary.’ ’’ (Citation omitted; emphasis
    added.) Id., 980; see also Ayers v. Jackson, supra, 
    106 N.J. 606
     (‘‘we hold that the cost of medical surveillance
    is a compensable item of damages [when] the proofs
    demonstrate, through reliable expert testimony predi-
    cated upon the significance and extent of exposure to
    chemicals, the toxicity of the chemicals, the seriousness
    of the diseases for which individuals are at risk, the
    relative increase in the chance of onset of disease in
    those exposed, and the value of early diagnosis, that
    such surveillance to monitor the effect of exposure to
    toxic chemicals is reasonable and necessary’’ (empha-
    sis added)); P. Lin, Note, ‘‘Opening the Gates to Scien-
    tific Evidence in Toxic Exposure Cases: Medical Moni-
    toring and Daubert,’’ 
    17 Rev. Litig. 551
    , 582 (1998)
    (‘‘[a]lthough claims for medical monitoring damages do
    not require proof of specific causation, the plaintiff’s
    burden includes proof of medical necessity, which is
    similar to proof of specific causation in that it shows
    that the individual plaintiff can benefit from a program
    of medical monitoring’’).21 Requiring each plaintiff to
    prove ‘‘reasonable necessity’’ is vital, as the clinical
    suitability of medical monitoring must be established
    because, if such monitoring is unnecessary, recovery
    would be unwarranted.
    The plaintiffs’ argument that experts ‘‘should not
    form any opinions about the plaintiffs’ exposure and
    their need for medical monitoring . . . because that
    function should be reserved to the trier of fact’’ is
    against the weight of persuasive authority.22 This is the
    very purpose of expert testimony in medical monitoring
    cases. ‘‘[I]t is for the trier of fact to decide, on the basis
    of competent medical testimony, whether and to what
    extent the particular plaintiff’s exposure to toxic chemi-
    cals in a given situation justifies future periodic medical
    monitoring.’’ (Emphasis added.) Potter v. Firestone
    Tire & Rubber Co., supra, 
    6 Cal. 4th 1009
    . Expert testi-
    mony limited to ‘‘generally inform[ing] lay jurors about
    the scientific correlation between asbestos exposure
    and the onset of asbestos related diseases,’’ as the plain-
    tiffs argue, is inadequate proof as a matter of law. In
    the absence of expert testimony demonstrating the
    necessity of future testing, a fact finder would be unable
    to accurately conclude whether a plaintiff should
    recover for medical monitoring. As the court in Hansen
    noted, exposure alone does not provide a basis for
    recovery, and proof of these elements, through expert
    testimony, provides an important check on medical
    monitoring. See Hansen v. Mountain Fuel Supply Co.,
    supra, 
    858 P.2d 978
    , 980; see also In re Paoli Railroad

    claims, such as demonstrating that ‘‘a reasonable physi-
    cian would prescribe for her or him a monitoring regime

     (1995).
    Attached as an exhibit to their motion for summary
    judgment, the defendants provided an excerpt of
    Anwar’s deposition testimony, in which he stated that
    he had not formed an opinion as to the plaintiffs. This
    admission establishes that there is no genuine issue
    of material fact as to whether medical monitoring is
    reasonably necessary for the plaintiffs. The plaintiffs
    attempted to counter the defendants’ evidentiary show-
    ing with an affidavit from Anwar, but that affidavit does
    not offer an opinion as to the plaintiffs, individually
    or as a group. There is only one statement that may
    reasonably be construed as relevant to the plaintiffs’
    claims: ‘‘Other individuals who were exposed to asbes-
    tos during the demolition work at Sikorsky should be
    monitored for the early detection and intervention of
    an asbestos related disease, as asbestos inhalation
    causes a significantly increased risk of contracting a
    serious disease . . . .’’ The only fact that this statement
    establishes is that persons exposed to asbestos have
    a significantly higher risk of contracting an asbestos
    related disease and should be monitored. This state-
    ment does not speak to the reasonable need for the
    medical monitoring of the plaintiffs, and it is insufficient
    to overcome summary judgment. But see In re Paoli
    Railroad Yard PCB Litigation, supra, 
    35 F.3d 794

    , 
    132 S. Ct. 499
    , 
    181 L. Ed. 2d 347
     (2011). In addition, the affidavit lacks any statement
    demonstrating that ‘‘early detection, combined with
    prompt and effective treatment, will significantly
    decrease the risk of death or the severity of the disease,
    illness or injury,’’ the fifth element required under Dono-
    van. Donovan v. Philip Morris USA, Inc., supra, 
    455 Mass. 226
    ; see In re Marine Asbestos Cases, 
    supra,
     
    265 F.3d 867
     (‘‘the plaintiffs have not shown that a treatment
    exists for [asbestos related] diseases, or that there is
    clinical value to administering any such treatment
    before the onset of symptoms of these diseases’’).
    Even if we were to conclude that Anwar’s affidavit
    was applicable to plaintiffs other than his patient, Dou-
    gan, the portions of the affidavit that could apply to
    the plaintiffs provide only bare assertions of the legal
    requirements of medical monitoring without providing
    the factual foundation supporting those assertions. In
    several places, the affidavit mirrors the language required
    to prove a medical monitoring claim in Redland Soccer
    Club, Inc. v. Dept. of the Army, 
    548 Pa. 178
    , 195–96,
    
    696 A.2d 137
     (1997). Specifically, the affidavit states
    that ‘‘[o]ther individuals who were exposed to asbestos
    . . . at Sikorsky should be monitored . . . as asbestos
    inhalation causes a significantly increased risk of con-
    tracting a serious disease . . . . The monitoring regi-
    men would be different from what is normally recom-
    mended in the absence of exposure . . . . [It] is
    reasonably necessary according to contemporary scien-
    tific principles, and the monitoring regimen makes early
    detection and intervention of an asbestos related dis-
    ease possible.’’ Although the affidavit does include
    detailed factual statements, those statements apply only
    to Dougan, who is no longer a plaintiff. Without addi-
    tional details supporting the plaintiffs’ individual needs
    for medical monitoring, the plaintiffs have not raised a
    genuine dispute of material fact.
    We have repeatedly held that such conclusory state-
    ments included in affidavits are insufficient to defeat
    a motion for summary judgment. See, e.g., Stuart v.
    Freiberg, supra, 
    316 Conn. 828
     (discussing how state-
    ments in affidavits relied on by plaintiffs ‘‘closely repli-
    cate portions of the pleadings’’ and how ‘‘these aver-
    ments are conclusory, and therefore inadequate to
    defeat a summary judgment motion’’); Coley v. Hart-
    ford, 
    312 Conn. 150
    , 166 n.12, 
    95 A.3d 480
     (2014) (con-
    cluding that expert’s affidavit was conclusory and,
    therefore, did not demonstrate genuine issue of material
    fact to defeat summary judgment motion); Buell Indus-
    tries, Inc. v. Greater New York Mutual Ins. Co., 
    259 Conn. 527
    , 557, 
    791 A.2d 489
     (2002) (‘‘[a]lthough an
    affidavit by an expert may be considered in opposition
    to a motion for summary judgment, conclusory affida-
    vits, even from expert witnesses, do not provide a basis
    on which to deny such motions’’ (internal quotation
    marks omitted)). Anwar’s affidavit does not provide
    any specific explanation as to why the plaintiffs require
    medical monitoring because of their asbestos exposure
    at Sikorsky.
    As the expert in this case provided no opinion as to
    the plaintiffs, and in the absence of any other evidence
    demonstrating the reasonable necessity of medical
    monitoring, we conclude that the plaintiffs did not dem-
    onstrate a genuine issue of material fact. Accordingly,
    we conclude that the trial court properly granted sum-
    mary judgment for the defendants.
    The judgment is affirmed.

    The named plaintiff, Danny Dougan, was the fifth plaintiff in the proceed-
    ings before the trial court. Dougan died in December, 2017, while his appeal
    was pending before the Appellate Court. Dougan was initially the only
    plaintiff to appeal, and, after he died, the defendants moved to dismiss the
    appeal. The defendants argued that Dougan’s claims for medical monitoring
    were moot and that, because he was the only plaintiff on appeal, the case
    should be dismissed. Carol Ann Slicer, the executor of Dougan’s estate,
    then filed a motion for leave to substitute herself for Dougan. The Appellate
    Court granted this motion. Dougan’s estate then filed an objection to the
    motion to dismiss, contending that the claims were not moot and that,
    because of technical difficulties, the other plaintiffs had not been named in
    the appeal. The Appellate Court granted the defendants’ motion to dismiss
    Dougan’s appeal but also permitted the remaining plaintiffs to file a late
    appeal, which is presently before this court. See footnote 3 of this opinion.
    As a result, we consider only the claims of the four remaining plaintiffs,
    and all references herein to the plaintiffs collectively are to them.
    2
    The plaintiffs withdrew their claims against the third defendant, URS
    Corporation AES, on July 30, 2019, during the pendency of this appeal. See
    footnote 6 of this opinion.
    3
    After receiving permission to file a late appeal; see footnote 1 of this
    opinion; the plaintiffs appealed from the judgment of the trial court to the
    Appellate Court, and we subsequently transferred the appeal to this court
    pursuant to General Statutes § 51-199 (c) and Practice Book § 65-1.
    4
    We note that the trial court considered the plaintiffs’ position as a request
    for a medical monitoring remedy rather than an independent cause of action.
    On appeal, the plaintiffs request either the recognition of a stand-alone cause
    of action or a remedy. Although there are some differences between the
    two approaches, the elements of proof for either approach to medical moni-
    toring are the same. See 1 J. McLaughlin, Class Actions (16th Ed. 2019) § 5:18
    (‘‘The distinction between recognizing medical monitoring as an independent
    cause of action and allowing it solely as a remedial measure has practical
    consequences. If medical monitoring is not an independent cause of action,
    then the plaintiff must establish all elements of an independent basis of
    recovery, and the defendants may assert all available affirmative defenses
    as against individuals. However, the elements of proof for medical monitor-
    ing as a cause of action and as a remedy remain the same and must be
    established by the plaintiffs.’’ (Footnote omitted.)).
    5
    The defendants contend that Ferrara was not involved in pipe demolition
    or removal and that he never entered the basement where the asbestos was
    found. Viewing the evidence in the light most favorable to the plaintiffs, we
    accept their argument that this is irrelevant, as asbestos was also found on
    the main floor of the boiler house and in an exterior dumpster, areas where
    Ferrara worked.
    6
    The initial complaint also named A/Z Corporation, Clean Harbors of
    Connecticut, Inc., and Clean Harbors Environmental Services, Inc., as defen-
    dants; the action was later withdrawn as to those parties.
    7
    The plaintiffs moved for class certification in July, 2013, and requested
    that the trial court certify a class of approximately forty persons who were
    allegedly exposed to asbestos during the Sikorsky cogeneration project. The
    defendants objected and submitted affidavits from two experts, Charles L.
    Blake, an industrial hygienist, and Mark Metersky, a pulmonologist. Specifi-
    cally, the defendants argued, inter alia, that the plaintiffs failed to demon-
    strate that common questions predominate, and, as such, class certification
    would be inappropriate. The trial court granted in part and denied in part the
    plaintiffs’ request to certify the class in February, 2016. In its memorandum
    of decision, the trial court concluded that the plaintiffs had not demonstrated
    sufficient commonality in their claims for medical monitoring due to certain
    individual inquiries, such as each ‘‘class member’s current medical condition
    . . . .’’ Nevertheless, the court proceeded to certify the class but excluded
    certain issues from class treatment, such as a class member’s need for
    medical monitoring. Simultaneously, the court also granted in part and
    denied in part motions to strike filed by Sikorsky and Carrier, striking the
    plaintiffs’ federal Clean Air Act claims but permitting their other strict
    liability claims to proceed.
    8
    Shortly thereafter, URS filed its second motion for summary judgment,
    asserting largely the same claims as Sikorsky and Carrier. URS had filed
    its first motion for summary judgment in 2014, but the trial court did not
    decide this motion before granting URS’ second motion for summary judg-
    ment on March 28, 2017.
    9
    The defendants raised this issue as an alternative ground to affirm the
    trial court’s judgment in their preliminary statement of the issues pursuant
    to Practice Book § 63-4 (a) (1); they also raised this issue before the trial
    court in their motion for summary judgment. See, e.g., Thomas v. West
    Haven,

    , 390–91 n.11,

    Medical monitoring differs doctrinally from a claim for enhanced risk.

    Monitoring To Detect or Prevent Future Disease or Condition,’’ 
    17 A.L.R.5th 327
    , 336, § 2 (a) (1994) (‘‘[m]edical monitoring, as this cause of action has
    come to be known, has been defined as an action seeking to recover the
    quantifiable costs of periodic future medical examinations to detect the
    onset of physical harm . . . as distinguished from an enhanced risk claim
    which seeks compensation for the anticipated harm itself or for increased
    apprehension of such harm’’ (internal quotation marks omitted)).

    1988) (‘‘In a toxic tort case the significant personal injuries often are not

    are latent. In fact, most toxic injuries do not manifest themselves as clinically

    1216 (D. Colo. 2018) (disagreeing with plaintiffs’ theory that ‘‘the bioaccumu-

    59 Stan. L. Rev. 1671
    , 1674 (2007) (‘‘Although the case
    law addressing subcellular damage is limited . . . most courts have treated
    such damage as benign, de minimis, or otherwise legally inconsequential.
    Courts greatly prefer to draw bright lines between risk and injury, and
    continue to place the boundary at proof of classic medical symptoms or
    overt impairment.’’ (Footnote omitted.)). But see Sullivan v. Saint-Gobain
    Performance Plastics Corp., 
    431 F. Supp. 3d 448
    , 454–55 (D. Vt. 2019) (‘‘It
    is more likely that the Vermont Supreme Court will follow the definition of
    bodily harm developed in [§ 15 of] the Restatement [(Second) of Torts] and
    apply it to latent injuries caused by chemical exposure. By defining bodily
    harm to include any alteration to a person’s body, the Restatement [(Second)
    of Torts] includes changes such as abnormal blood serum results showing
    the presence of an unusual and potentially harmful chemical.’’).
    One Connecticut trial court has held that a very similar theory of liability
    in an asbestos exposure case raised a question of fact for the jury to decide.
    See Bowerman v. United Illuminating, Superior Court, judicial district of
    New London at Norwich, Docket No. CV-XX-XXXXXXX-S (December 15, 1998)
    (
    23 Conn. L. Rptr. 589
    , 592) (‘‘whether . . . the scarring of lung tissue and
    implantation of asbestos fibers in the lungs constitute a compensable legal
    harm is an issue of fact if there is evidence showing such conditions to be
    detrimental and if there is evidence showing the existence of such conditions
    in the plaintiffs’’).
    17
    We note that other federal and state courts have employed a similar
    analysis, deeming it unnecessary to determine whether to recognize a claim
    for medical monitoring because the plaintiffs’ proof was inadequate to defeat
    a motion for summary judgment in any event. See M.G. ex rel. K.G. v. A.I.
    duPont Hospital for Children, 
    393 Fed. Appx. 884
    , 892–93 (3d Cir. 2010)
    (declining to consider whether Delaware Supreme Court would permit medi-
    cal monitoring claim because plaintiff could not state such claim); In re
    Marine Asbestos Cases, 
    265 F.3d 861
    , 867 (9th Cir. 2001) (upholding grant
    of summary judgment because, ‘‘even if medical monitoring were available
    under the Jones Act to a seaman who satisfied the Paoli factors, the plaintiffs
    have failed to present sufficient evidence to raise a genuine issue of material
    fact as to the reasonableness and necessity of the type of medical monitoring
    that they seek’’); DeStories v. Phoenix, 
    154 Ariz. 604
    , 610, 
    744 P.2d 705
     (App.
    1987) (upholding grant of summary judgment after concluding that, even if
    plaintiffs’ medical monitoring theory was legally cognizable, plaintiffs’ claim
    would still fail due to lack of evidence); cf. Philip Morris, Inc. v. Angeletti,
    
    358 Md. 689
    , 782, 787, 
    752 A.2d 200
     (2000) (declining to consider whether
    ‘‘medical monitoring is a cognizable claim’’ under Maryland law because
    medical monitoring class was improperly certified).
    18
    One federal district court recently rejected a defendant’s argument that
    there must be more individualized expert testimony as to causation. See
    Sullivan v. Saint-Gobain Performance Plastics Corp., 
    431 F. Supp. 3d 448
    ,
    467–70 (D. Vt. 2019). After first predicting that the Vermont Supreme Court
    would recognize a medical monitoring remedy, the court denied the defen-
    dant’s motion for summary judgment on the medical monitoring claims of
    a class of plaintiffs who allegedly had been exposed to perfluorooctanoic
    acid (PFOA) in their groundwater. 
    Id., 452
    , 469–70. The defendant argued
    that the plaintiffs lacked expert evidence demonstrating specific causation,
    specifically, that ‘‘that exposure to PFOA from the [defendant’s] facility
    caused [the plaintiffs to be exposed to] an increased risk of adverse health
    conditions, as opposed to whether it can do so in general.’’ (Emphasis
    omitted; internal quotation marks omitted.) 
    Id., 467
    . The court concluded
    that, although the plaintiffs’ experts had not reviewed the ‘‘individual plain-
    tiffs’ medical records,’’ summary judgment was inappropriate because ‘‘proof
    of causation must . . . be at the population level’’; 
    id.,
     467–68; and declined
    to grant summary judgment against any specific plaintiff because any individ-
    ual issues could be resolved at the damages phase. 
    Id.,
     469–70.
    We conclude that Sullivan is distinguishable. First, the class in that case
    was limited to individuals ‘‘who actually demonstrate[d] increased levels of
    PFOA in their bloodstream,’’ whereas the present case provides no such
    benchmark. 
    Id., 462
    . Second, although the case before us was a class action
    when the trial court decided the summary judgment motion, the trial court
    expressly declined to certify the class on the issue of ‘‘the nature and extent
    of [each class member’s] present or future need for medical monitoring
    . . . .’’ For these reasons, Sullivan is a case more appropriately decided
    by common proof, and we are not persuaded that it is applicable or persua-
    sive here.
    19
    Anwar did examine and treat Dougan as his pulmonary specialist, and,
    as a result, the affidavit does detail more specifically Dougan’s exposure to
    asbestos and the accompanying harm. Dougan therefore would likely satisfy
    the subcellular injury requirement under the Donovan standard. But, as
    Dougan is no longer a party to the case; see footnote 1 of this opinion; we
    do not consider the affidavit’s statements as to Dougan.
    20
    Medical necessity is demonstrated through the eighth element of Han-
    sen, that the ‘‘[medical] test has been prescribed by a qualified physician
    according to contemporary scientific principles.’’ Hansen v. Mountain Fuel
    Supply Co., supra, 
    858 P.2d 979
    .
    21
    We need not address how the reasonable necessity requirement would
    operate in the context of a class action involving a claim for future medical
    monitoring. The plaintiffs were not certified as a class with respect to this
    issue, and the appropriate treatment of class based claims for medical
    monitoring is not presented in this appeal. See footnote 7 of this opinion.
    As a result, we conclude that each plaintiff in the present case must establish
    that medical monitoring is necessary under the Donovan test and leave for
    another day under what circumstances reasonable necessity may be proven
    for a class of plaintiffs.
    22
    The plaintiffs also argue that experts should not opine as to ‘‘the [plain-
    tiffs’] likelihood of contracting diseases . . . .’’ Certain courts that permit
    medical monitoring have expressly stated that they do not require a specific
    assessment or showing of the likelihood of contracting a particular disease
    in the future. See Merry v. Westinghouse Electric Corp., 
    684 F. Supp. 847
    ,
    851 (M.D. Pa. 1988) (concluding that ‘‘the plaintiffs . . . proffered sufficient
    evidence to defeat [the defendant’s] summary judgment motion,’’ even
    though ‘‘[t]he [plaintiffs’] experts have not provided, and in fact state they
    cannot provide, a scientifically sound conclusion as to the precise degree
    of risk faced by the plaintiffs’’); Potter v. Firestone Tire & Rubber Co., supra,
    
    6 Cal. 4th 1008
     (concluding that ‘‘recovery of medical monitoring damages
    should not be dependent upon a showing that a particular cancer or disease
    is reasonably certain to occur in the future’’); Hansen v. Mountain Fuel
    Supply Co., supra, 
    858 P.2d 979
     (‘‘[b]ecause the injury in question is the
    increase in risk that requires one to incur the cost of monitoring, the plaintiff
    need not prove that he or she has a probability of actually experiencing the
    toxic consequence of the exposure’’). We agree with the plaintiffs that expert
    testimony on that particular issue is not necessary in this particular context.
