Prostate-Specific Antigen (PSA) Test

A Prostate-Specific Antigen (PSA) test measures the level of PSA, a protein produced by the prostate gland, in your blood. Elevated PSA levels can indicate prostate issues, including benign conditions like inflammation or enlargement, as well as prostate cancer. The test helps doctors evaluate prostate health and decide if further investigation is needed. It is commonly used for screening in men, especially those at higher risk for prostate problems. However, because PSA levels can be influenced by various factors, the test is one part of a comprehensive assessment rather than a standalone diagnosis.
