What is the typical reference range for male hemoglobin in g/dL?

• A. 8-10
• B. 12-14
• C. 14-18
• D. 20-24

Answer: (A)

Hemoglobin level reflects the blood’s oxygen-carrying capacity, and for adult men the normal range sits in the mid-teens. Most labs cite about 13.5–17.5 g/dL, with many using 14–18 g/dL as the common window. Values well below this indicate anemia, while values well above suggest polycythemia or other conditions. So the typical reference range is around 14–18 g/dL, not the lower or higher extremes like 8–10 or 20–24 g/dL. Variations can exist by lab and altitude, but the mid-teens is the standard idea.
