Glossary Definition

Definition:

The positive predictive value of a test is the probability that the patient/subject has the disease/condition when restricted to those patients/subjects who test positive. This term is sometimes abbreviated as PPV. You can compute the positive predictive value as PPV = TP / (TP + FP) where TP and FP are the number of true positive and false positive results, respectively. Notice that the denominator for positive predictive value is the number of patients/subjects who test positive.
