The tests include a PSA (prostate specific antigen) blood test and a rectal examination. A PSA test is not a very accurate test for prostate cancer. Some men with a high level of PSA in the blood have prostate cancer. But some men who have prostate cancer have a low PSA level.
Free PSA Test Helps in Prostate Cancer Diagnosis by William J. Catalona, M.D. A relatively new and helpful addition in the diagnosis of prostate cancer is the free PSA Test. This blood test is done in addition to the PSA Test and the finger (digital) examination. The PSA Test measures a protein in the blood that is produced only by the prostate gland. Some of the PSA in blood is bound to other proteins and the rest circulates freely. This free PSA is a damaged variant of PSA that no longer is able to bind to other proteins and thus circulates in the blood in the unbound (free) form.
