Is it normal for a male to have 15.6 hemoglobin?

Normal hemoglobin levels vary based on age, sex, and other factors. For adult males, normal hemoglobin levels generally range from 13.8 to 17.2 grams per deciliter (g/dL). A hemoglobin level of 15.6 g/dL falls within the normal range for adult males.

However, it's essential to keep in mind that hemoglobin levels can be affected by various factors such as altitude, smoking, certain medical conditions, and medications. If you have any concerns about your hemoglobin level or other health-related matters, it's always best to consult a healthcare professional for accurate information and personalized advice.
