13.5 to 18gm/dl. A man is 13.5 to 17.5 g/dl and … for a woman is 11.5 to 15.5 g/dl.
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. Answers-Russell Portenoy What is normal depends on the lab. Most women with hemoglobin above 14 or 14.5 would be considered to have a normal level. There are some new data to suggest that hemoglobin levels in the range of 10-12 are critically important in terms of the onset of fatigue. 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. 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 donor’s hemoglobin at the clinic and requires a minimum of 125 g/L for donation. 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.
