Prostate-Specific Antigen (PSA) (MALES ONLY) -
(QUEST DIAGNOSTICS)Description: Prostate-specific antigen (PSA) is a glycoprotein produced by the epithelial cells lining the prostatic ducts and acini. Normally, it is secreted into the prostatic ducts and is present only in prostate tissue, prostatic fluid, and seminal plasma. PSA is produced by normal, hyperplastic, and cancerous prostatic tissue. PSA is used as a tumor marker for the early detection of prostate cancer and in other areas of prostate disease management. Elevated serum PSA concentrations have been reported in men with prostate cancer, benign prostatic hypertrophy, and inflammatory conditions of the prostate.
The Prostate-Specific Antigen Best Practice Statement: 2009 Update published by the American Urologic Association describes the use of PSA testing for:
• The evaluation of men at risk for prostate cancer
• Assistance in pretreatment staging
• Risk assessment posttreatment monitoring
• Use as a guide in management of men who recur after primary or secondary therapy
Significant deviations from the normal range may require further evaluation by your physician.
Please Note: This test is for male clients only, due to ordering restrictions on certain tests, the PSA test will not be included on the requisition and will not be performed when ordered by females.
