PSA (Prostate-Specific Antigen) Screening

Prostate-Specific Antigen (PSA) is a protein produced by the cells of the prostate gland. The PAS test measures the level of PSA in the blood.

Our technicians take a blood sample, and the amount of the PSA is measured in a laboratory.

PSA test results are reported as nanograms of PSA per milliliter of blood (ng/mL).

This table shows the current classification of PSA levels. (These values may change in the coming years as more information is gained regarding the differences in "normal" PSA levels for men based on their age, family history, and race.)

Normal 0-4 ng/mL
Slightly elevated 4-10 ng/mL
Moderately elevated 10-20 ng/mL
Highly elevated 20 ng/mL or higher
