What is the Role of Predictive Values?


Positive Predictive Value (PPV) is the probability that individuals with a positive test result truly have the disease.
Negative Predictive Value (NPV) is the probability that individuals with a negative test result truly do not have the disease. These values are influenced by the prevalence of the disease in the population being tested.
