how does it take for a low hemoglobin to return to normal
If you have normal iron reserves and adequate iron in your diet, new red blood cells will be made and your hemoglobin level will return to normal in less than 56 days. It is important not to donate blood if the hemoglobin level is already low.n 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 donorâs hemoglobin at the clinic and requires a minimum of 125 g/L for donation.
