Our Prostate Cancer Screening blood test is a reliable and non-invasive way to assess your risk for prostate cancer. Prostate cancer is a common cancer among men, and early detection is crucial for successful treatment. Our test measures the levels of prostate-specific antigen (PSA) in your blood, which is a protein produced by the prostate gland. Elevated levels of PSA in the blood can indicate the presence of prostate cancer or other prostate conditions.
