Prostate-Specific Antigen (PSA), Free and Total (MALES ONLY) - (QUEST DIAGNOSTICS)
In this profile, free PSA is performed regardless of the concentration of total PSA. The interpretive guidelines provided for percent free PSA are based on a population of men with normal digital rectal exam (DRE) and total PSA between 4.0 and 10.0 ng/mL. Elevated levels of Prostate Specific Antigen (PSA) have been associated with benign and malignant prostatic disorders. Studies indicate that in men 50 years or older measurement of PSA is a useful addition to the digital rectal exam in the early detection of prostate cancer. In addition, PSA decreases to undetectable levels following complete resection of the tumor and may rise again with recurrent disease or persist with residual disease. Thus, PSA levels may be of assistance in the management of prostate cancer patients.
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.
