Prostate Specific Antigen

Prostate Specific Antigen is a protein that is found in measurable amounts in the bloodstream.  The quantity of PSA in the blood tends to correlate with the size of the prostate.  An enlarged prostate sometimes indicates a prostate problem.  It is possible to have a normal PSA result and still have a prostate problem.  Even an increase in PSA level that is still in the normal range can be an indication that their is a problem.  Your health care provider will discuss your results with you.

A normal PSA level is 0.0 - 4.0 ng/mL
