Is This Medical Test Valid?

Understand what your gyno is looking at to figure out the statistics. The test is sensitive if it accurately distinguishes who has the disease vs  specific if it really says who does not have the disease. A test has positive predictive value if it predicts who with the disease really has it and it has negative predictive value if it can say, statistically well, that a person with a negative test really does not have the disease. Once a physician knows these factors she can either recommend the test, or not recommend the test for you based on your medical history.
