The positive and negative predictive values ​​(PPV and NPV, respectively) are the percentage of positive and negative results in statistical and diagnostic tests that are true positives and true negatives, respectively. [1] PPV and NPV describe the performance of a diagnostic test or another statistical measure.

A high result can be interpreted as an indication of the accuracy of such statistics. PPV and NPV are not test-specific (as opposed to true positive and true negative rates). It also depends on prevalence [2]. Both PPV and NPV can be derived using Bayes' theorem.

Sometimes used interchangeably, positive predictive value usually refers to that found by a control group, and post-test probability refers to individual probability.
