PSA Test: What It Shows and What It Does Not
Quick answer: Prostate specific antigen is a protein made by the prostate. A PSA test is used as a screening tool for prostate problems. A higher PSA does not mean cancer, and a normal PSA does not rule it out.
About this test
The test measures PSA in your blood. Small amounts are normal. PSA tends to rise with age and with prostate size.

What this test may not show
