What is the normal adult Hb range for men?

• A. 12–17 g/dL
• B. 10–14 g/dL
• C. 14–18 g/dL
• D. 8–12 g/dL

Answer: (A)

Hemoglobin levels reflect the blood’s capacity to carry oxygen to tissues. For adult men, a typical healthy range is about 13.5–17.5 g/dL. The range 12–17 g/dL aligns with commonly used reference values as a broad normal span for men, capturing the usual variability between individuals and laboratories. Values lower than this can indicate anemia, while higher values could indicate polycythemia; the other options fall outside what is generally considered normal for healthy adult men. This makes the 12–17 g/dL range the best choice.
