Prostate-specific antigen (PSA) is a protein that is produced by the prostate gland. Higher levels of PSA can sometimes be an indicator of prostate cancer. This test includes measurements for PSA, Free PSA and % Free PSA. This blood test is used to aid in diagnosing and monitoring the treatment of prostate cancer. However, not all cases of prostate cancer will cause elevated PSA levels and there are conditions other than cancer which may cause elevated PSA. Other noncancerous conditions that can caused elevated PSA levels are inflammation of the prostate and enlargement of the prostate.

- PSA Free and total
The free & total PSA test provides a more detailed evaluation of prostate health. The percentage of measured prostate-specific antigen (PSA) existing in the free form (free: total PSA ratio) is useful in assessing the risk of prostate cancer in patients with borderline or moderately increased total PSA (4.0-10.0 ng/mL) and has been used to help select men who should have a follow-up prostate biopsy.
The turnaround for this test is typically 1-3 business days.
