How It's Done
Blood for a PSA test usually is drawn from a vein in the crook of your elbow. The area from which blood will be taken will be cleaned with an alcohol swab. A sterile needle will be used to draw a few ounces of blood into a tube. The puncture site will be covered with a small gauze or bandage. Your blood sample will be sent to a lab where the PSA level is measured.
