variability in test performance

What is Positive Predictive Value (PPV) and Negative Predictive Value (NPV)?

PPV and NPV provide additional context on test performance:

Positive Predictive Value (PPV): The probability that a person with a positive test result actually has the disease.
Negative Predictive Value (NPV): The probability that a person with a negative test result truly does not have the disease.

These values are influenced by the prevalence of the disease in the population being tested.
