Normal hemoglobin levels are different in women and in men. In non-pregnant women, normal hemoglobin ranges from 120 g/L to 160 g/L. In men, normal hemoglobin levels range from 140 g/L to 180 g/L. Canadian Blood Services tests each donorâs hemoglobin at the clinic and requires a minimum of 125 g/L for donation.n men, normal hemoglobin levels range from 140 g/L to 180 g/L.

Hemoglobin Levels for Adults. According to the World Health Organization, a normal hemoglobin level for an adult male is between 13.8 and 17.2 g/dL. A normal level for a non-pregnant adult woman is between 12.1 and 15.1 g/dL. Men have higher hemoglobin levels than women because women lose red bloods each month during menstruation. A normal level for a pregnant woman is at or above 11.0 g/dL. During pregnancy, blood volume increases by 40 to 50 percent, but the red blood cell count increases by just 15 to 20 percent.
