Positive Predictive Value: Doctor, I have a positive test outcome, now what is the chance that I really do have the disease? This is also the time to evaluate reliability measures and search for a positive-test threshold for continuous measures. A subsequent diagnostic test either increases or decreases the prior risk, so that the physician can feel confident about the presence or absence of a specific disease and act accordingly (either treat the disease or repeat the same process for another disease in the differential diagnosis).
