Prostate Specific Antigen (PSA)
To screen for prostate cancer.
A prostate-specific antigen (PSA) blood test measures the amount of prostate-specific antigen in the blood. PSA is released into a man’s blood by his prostate gland. Healthy men usually have low amounts of PSA in the blood. The amount of PSA in the blood normally increases as a man’s prostate enlarges with age. A PSA level within the normal ranges does not mean that prostate cancer is not present. Also, some men with prostate cancer have normal PSA levels.
