Prostate Specific Antigen (PSA) Free with Total Ratio
This panel contains the following tests:
Prostate specific antigen (PSA) is produced exclusively by cells of the prostate gland. Used in conjunction with the digital rectal examination, PSA is a useful screening test for benign prostate hyperplasia (BPH) and prostate cancer development.
Free PSA is a newer evaluation for prostate health. This test is used to measure the percentage of free PSA relative to the total amount. Although not used as an initial screening test, a lower percentage of free PSA might mean your doctor needs to do a further testing on the prostate gland.
Fasting is not required for this test. Take all medications as prescribed.
Ejaculation within 48 hours preceding the blood draw may elevate the PSA in some men.
