The normal range of hemoglobin in male is 13.5 to 18gm/dl, female it is 12 to 16gm/dl and children is 11 to 16gm/dl.
The hemoglobin level is expressed as the amount of hemoglobin in grams (gm) per deciliter (dL) of whole blood, a deciliter being 100 milliliters. The normal ranges for hemoglobin depend on the age and, beginning in adolescence, the gender of the person. Normal hemoglobin values are related to the person's age and sex. Normal values may vary slightly between test systems, and which groups of doctors have determined normal values for their group of patients; however, the value ranges are close (vary by about 0.5 g/dl) for almost every group. Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hemoglobin is made up of four protein molecules (globulin chains) that are connected together. The normal hemoglobin range for women is slightly on the lower side compared to that of men. This is because, women lose blood during menstruation. Normal hemoglobin level tends to rise slightly during pregnancy, as there is an increased need for oxygen in the body. The normal range of hemoglobin (also haemoglobin) varies in men, women, and children. The normal range of hemoglobin in male is 13.5 to 18gm/dl (gram per deciliter). For female it is 12 to 16gm/dl (gram per deciliter). In a children 11 to 16gm/dl (gram per deciliter). And for a pregnant woman 11 to 12g/dl (gram per deciliter) is the normal range of hemoglobin. If the hemoglobin is below normal, this is called anemia. For people without diabetes, the normal range for the hemoglobin A1c test is between 4% and 5.6%. Hemoglobin A1c levels between 5.7% and 6.4% indicate increased risk of diabetes, and levels of 6.5% or higher indicate diabetes.
