  • The assessment of serum levels of prostate specific antigen (PSA) has become an important part of early detection of prostate cancer. Among all laboratory markers of cancer, PSA is the most widely used and most clinically useful. However, the test is not perfect, and depending on the population studies, can have 65% false positives, and at least 20% false negative results. In this article, information will be presented on a variety of molecular forms of PSA, and different ways of studying PSA, in order to improve the diagnostic accuracy of the test.
