Term: Negative Predictive Value (NPV)
Glossary Definition
Last Updated: 20061020
Definition:
The negative predictive value of a test is the probability that the patient will not have the disease/condition when restricted to all patients/subjects who test negative. You can compute the negative predictive value as NPV = TN / (TN + FN) where TN and FN are the number of true negative and false negative results, respectively. Notice that the denominator for negative predictive value is the number of patients/subjects who test negative.
