(b) The toxicity of the chemical(s);
(c) The relative increase in [name of plaintiff]’s chance of getting the
disease as a result of the exposure, when compared to:
(i) [his/her] chances of developing the disease had [he/she] not
been exposed, and
(ii) the chances that members of the public at large will develop

Sources and Authority
• “In the context of a toxic exposure action, a claim for medical monitoring seeks
to recover the cost of future periodic medical examinations intended to facilitate
early detection and treatment of disease caused by a plaintiff’s exposure to toxic
substances.” (Potter v. Firestone Tire and Rubber Co. (1993) 6 Cal.4th 965,
1004–1005 [25 Cal.Rptr.2d 550, 863 P.2d 795], internal citation omitted.)
• “[W]e hold that the cost of medical monitoring is a compensable item of
damages where the proofs demonstrate, through reliable medical expert
testimony, that the need for future monitoring is a reasonably certain
consequence of a plaintiff’s toxic exposure and that the recommended
monitoring is reasonable. In determining the reasonableness and necessity of
monitoring, the following factors are relevant: (1) the significanc and extent of
the plaintiff’s exposure to chemicals; (2) the toxicity of the chemicals; (3) the
relative increase in the chance of onset of disease in the exposed plaintiff as a
result of the exposure, when compared to (a) the plaintiff’s chances of
developing the disease had he or she not been exposed, and (b) the chances of
the members of the public at large of developing the disease; (4) the seriousness
of the disease for which the plaintiff is at risk; and (5) the clinical value of
early detection and diagnosis. Under this holding, it 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 chemicals in a given situation
justifie future periodic medical monitoring.” (Potter, supra, 6 Cal.4th at p.
• “The crucial distinction, in other words, is in the nature of the monitoring, not
the nature of the harm. ‘[E]ven if a defendant negligently exposes a smoker to
toxins that significantl increase the smoker’s risk of cancer, that defendant is
not liable for reasonably certain future medical monitoring costs unless the
recommended monitoring calls for tests or examinations that are in addition to
or different from the type of monitoring that the smoker should prudently
undertake regardless of the subsequent toxic exposure.’ This accords with the
policy concern being addressed in that part of [Potter], which was to avoid
‘open[ing] the floodgate of litigation.’ If ‘the plaintiff already remains
responsible for any monitoring that is shown to be medically advisable due
solely to his or her smoking or other preexisting condition,’ he or she will have
no incentive to sue for contribution from a subsequent tortfeasor who has
caused no need for additional or different monitoring.” (Gutierrez v. Cassiar
Mining Corp. (1998) 64 Cal.App.4th 148, 156 [75 Cal.Rptr.2d 132], internal
citations omitted.)
