Priority Lab Testing offers a reliable method of prostate testing with individual prostate tests. These tests screen for prostate-specific antigens (PSA) to identify signs of prostate cancer or measure the effectiveness of treatment. Higher PSA levels may indicate the presence of cancer or an inflamed prostate gland. Symptoms of prostate cancer include but are not limited to difficulty urinating, frequent urination and erectile dysfunction. A prostate test is typically recommended for men over the age of 50 or individuals at risk for prostate cancer.
