predictive value

the conditional probability that a clinical test result correctly identifies a patient as having or not having a disease, i.e., the predictive value of a positive test (positive predictive v.) is the probability that a person with a positive test is a true positive (i.e., does have the disease) and the predictive value of a negative test (negative predictive v.) is the probability that a person with a negative test does not have the disease. Cf. sensitivity and specificity. The predictive value of a screening test is determined by the sensitivity and specificity of the test, and by the prevalence of the condition for which the test is used.
