Our Prostate Check blood test measures your Total PSA, Free PSA, and PSA Calculated Ratio to help detect early signs of prostate cancer. Total PSA is a protein produced by the prostate gland, and elevated levels may indicate the presence of cancer cells. Free PSA is a subtype of Total PSA that is not bound to other proteins, and a higher percentage of Free PSA in the blood can suggest a lower risk of cancer. The PSA Calculated Ratio combines both Total and Free PSA levels to provide a more accurate assessment of prostate cancer risk. With our Prostate Check, you can take proactive steps towards maintaining your prostate health.
