PSA, Total

Alternative Name:

Prostate Specific Antigen (PSA)

Clinical Utility:

Prostate specific antigen, produced by the prostate gland, is most useful for monitoring patients for residual disease after radical prostatectomy. PSA values should be <0.05 ng/mL if the entire prostate has been removed. PSA levels above 4 but less than 10 ng/mL are considered to be in the "grey zone". Elevations of PSA may indicate prostate cancer or could be the result of an infection or benign prostate enlargement. Refer also to BioReference test codes J254 and J264 for PSA that reflexes to the 4K score when PSA values exceed 1.5 and 3.0 respectively.
