The Free PSA % Test measures the levels of free PSA and total PSA in the blood to calculate the ratio of free to total PSA. PSA (Prostate-Specific Antigen) is an enzyme produced by the prostate gland, primarily found in semen, with trace amounts in the bloodstream. This test helps differentiate between prostate cancer and benign prostate conditions such as benign prostatic hyperplasia (BPH) or prostatitis. A lower ratio of free PSA to total PSA is often associated with an increased risk of prostate cancer.

Low Free-to-Total PSA Ratio: Indicates a higher risk of prostate cancer; further diagnostic tests may be needed. High Free-to-Total PSA Ratio: Suggests a lower likelihood of prostate cancer, potentially indicative of benign prostate conditions. Conditions Monitored: Prostate cancer risk Benign prostatic hyperplasia (BPH) Prostatitis Consult your doctor for a detailed interpretation and to plan the next steps if abnormalities are found.
