What is the normal range for hemoglobin in adult males?

12-16 g/dL
13.5-17.5 g/dL
14-18 g/dL
15-19 g/dL

The correct answer is: 13.5-17.5 g/dL

The normal range for hemoglobin in adult males is 13.5 to 17.5 g/dL. This range is established based on various studies and reflects the average levels found in healthy adult males. Hemoglobin is a critical protein in red blood cells responsible for the transport of oxygen throughout the body, and its concentration can indicate various health conditions, including anemia and polycythemia. In this context, understanding normal hemoglobin levels is especially important for clinicians in diagnosing and managing patient health, as abnormal values can guide further testing and treatment options. Hemoglobin levels can vary based on factors such as altitude, hydration status, and biological variability, which is why having an established normal range assists in clinical interpretations. The preference for the slightly narrower range of 13.5 to 17.5 g/dL aligns with current medical guidelines and laboratory standards for assessing hemoglobin levels in adult males.
