The normal level of hemoglobin in blood varies in male and female. In male it ranges from 13.8 to 17.2 gm/dL and in female it ranges from 12.1 to 15.1 gm/dL.Low level of Hemoglobin-There are many reasons for the reduction of hemoglobin blood.
A high hemoglobin level for a man would be above 18 g/dl and a woman 15 g/dl. If your hemoglobin is below those levels and above the average, then there is likely no problem. High hemoglobin levels can occur naturally if you live or have traveled recently to high altitudes where oxygen levels are low. The low oxygen stimulates your body to produce more red blood cells which have the hemoglobin.
