PSA (At-Home Kit)
Prostate specific antigen (PSA) is produced exclusively by cells of the prostate gland. The blood test for PSA is commonly ordered as a screening test for prostate cancer. A high PSA level may indicate the need for further evaluation.
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.
