Prostate-specific antigen (PSA) is a glycoprotein that is produced by the prostate gland, the lining of the urethra, and the bulbourethral gland. Normally, very little PSA is secreted in the blood. Increases in glandular size and tissue damage caused by benign prostatic hypertrophy, prostatitis, or prostate cancer may increase circulating PSA levels.
No special preparation is needed for PSA Total. Inform your doctor if you are on any medications or have any underlying medical conditions or allergies before undergoing PSA Total. Your doctor depending on your condition will give specific instructions.
