Clinical Notes

A PSA test can determine if you have high levels of PSA in your blood. Normally, PSA is produced and released within the prostate gland, where it helps make semen and plays an important role in fertility. Only small amounts of PSA move out of the prostate and into the blood in healthy people, but several prostate conditions can cause higher levels of PSA in the blood.
