Prostate Specific Antigen Screening

Meaning

Prostate Specific Antigen Screening is a clinical laboratory procedure that measures the concentration of Prostate Specific Antigen (PSA), a protein produced by both normal and malignant prostate cells, in a male’s blood serum. This test is a primary tool used to screen for and monitor prostate cancer, as elevated or rapidly rising PSA levels can indicate prostate disease, though not exclusively malignancy. The screening provides a quantifiable biomarker for assessing prostate health status.
