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.
The PSA test and DRE cannot, in general, predict the course of a person's disease. PSA exists in two main forms in the blood: complexed (cPSA, bound to other proteins) and free (not bound). The most frequently used PSA test is the total PSA, which measures the sum of complexed and the free PSA in the blood.
