What is the normal level for Prostate-Specific Antigen (PSA) in men?

• A. Less than 1 ng/mL
• B. Less than 2 ng/mL
• C. Less than 4 ng/mL
• D. Less than 6 ng/mL

Answer: (C)

Prostate-Specific Antigen (PSA) is a protein produced by both normal and malignant cells of the prostate gland, and its levels in the blood can be an important marker for prostate health. The typical cutoff for normal PSA levels in men is generally considered to be less than 4 ng/mL. Levels at or below this threshold are designated as being within normal limits, whereas levels above this number may warrant further investigation for potential prostate issues, including benign prostatic hyperplasia (BPH) or prostate cancer. This standard is used widely in clinical practice to help guide physicians in screening and monitoring prostate health. While PSA levels can vary based on individual circumstances, those under 4 ng/mL are generally interpreted as more secure in terms of prostate health. Hence, the correct choice aligns with the established medical benchmarks for PSA levels in men.
