What is the normal hemoglobin range for adult males?

• A. 12-16 g/dL
• B. 13-17 g/dL
• C. 14-18 g/dL
• D. 11-15 g/dL

Answer: (B)

Adult males typically have a higher hemoglobin level than females because androgens stimulate red blood cell production. The standard reference range for adult men is about 13 to 17 g/dL (some labs round to 13.5–17.5). This range best matches the common clinical reference used across many settings. Values below this range can indicate anemia, while values above can point to polycythemia, dehydration, or adaptation to high altitude. The other options either start too low or end too high for the typical male reference.
