What are normal hemoglobin levels in a human?

Answer by  astrojazz (367)

For a normal and healthy adult woman you should have hemoglobin levels between 120 grams per liter and 160 grams per liter. For men it should be between 140 grams per liter and 180 grams per liter. If your hemoglobin levels are outside of this range you should consult you doctor immediately.

For men, the normal range is 13.8 to 17.2. For women, it is 12.1 to 15.1. High levels could indicate heart disease, while low levels can be anemia or malnutrition.
