Test Overview
Test Methodology

Chemiluminescent Immunoassay (CLIA)

Test Usage

May aid as a marker for prostate cancer. Do not use as a screening procedure as PSA has been observed in patient's with benign prostatic hypertrophy. Diagnostic PSA (DPSA) should be utilized for patients with a diagnosis of prostate cancer.

Reference Range *

MALE: Age 0 - 49 yrs: < 2.5 ng/mL, Age 50 - 59 yrs: < 3.5 ng/mL, Age 60 - 69 yrs: < 4.5 ng/mL, Age 70 - 150 yrs: < 6.5 ng/mL. FEMALE: Age 0 - 150 yrs: < 0.1 ng/mL.
