What does the Prostatic Specific Antigen (PSA) test measure?

The Prostate-Specific Antigen (PSA) test measures the amount of PSA, a protein produced by both normal and malignant cells of the prostate gland, present in the blood. Elevated levels of PSA can indicate various prostate conditions, including benign prostatic hyperplasia, prostatitis, and prostate cancer. The test is valuable for monitoring prostate health and guiding further diagnostic procedures if necessary.

Understanding the role of PSA in the bloodstream is crucial because it helps healthcare providers evaluate a patient's risk for prostate-related issues and determine appropriate next steps in their care. By measuring the quantity of this antigen, clinicians can identify potential problems, even in the absence of symptoms.
