Mentioned in: Genetic Testing

predictive value

a measure used by clinicians to interpret diagnostic test results. See also sensitivity, specificity.

positive predictive value

the probability that a patient with a positive test result really does have the condition for which the test was conducted.

negative predictive value

the probability that a patient with a negative test result really is free of the condition for which the test was conducted.

positive predictive value

Statistics The number of true positives divided by the sum of true positives–TP and false positives–FP, a value representing the proportion of subjects with a positive test result who actually have the disease, aka 'efficiency' of a test.

genetic testing PPV predictive value value			They found that response of the tumour to treatment with PET-CT had a sensitivity (rate of true positives) of 83 percent, specificity (rate of true negatives) of 54 percent, positive predictive value (probability that patients who test positive have the disease) of 31 percent and negative predictive value (probability that patients who test negative do not have the disease) of 92 percent.
