Preparation: No special preparation or fasting required, but avoid ejaculation, vigorous exercise, or any prostate manipulation (e.g., digital rectal exam) 24-48 hours before the test, as these can affect PSA levels.

Procedure: A simple blood draw from a vein in the arm.

Description

The Prostate Specific Antigen (PSA) test measures the level of PSA in the blood, a protein produced by the prostate gland. It is commonly used to screen for prostate cancer, monitor the effectiveness of treatment, and detect prostate conditions like benign prostatic hyperplasia (BPH) or prostatitis.
