The Free Prostate-Specific Antigen (Free PSA) test measures the level of free PSA in the blood, which is primarily produced by prostate cells. This test is used as a tool to assess prostate health and is considered an important part of prostate cancer screening, especially in men with elevated total PSA levels. The Free PSA test helps distinguish between benign conditions, such as benign prostatic hyperplasia (BPH), and prostate cancer. While elevated total PSA levels may indicate the presence of cancer, higher levels of free PSA often suggest non-cancerous conditions. This test is usually recommended following total PSA results, as it provides additional information about a man’s prostate health and aids in making more accurate treatment decisions. The Free PSA test is an important tool for monitoring prostate health and tracking patients at risk for prostate cancer.
