In normal pregnancy the mean fetal haemoglobin increases linearly from 11 g/dl at 17 weeks' gestation to 15 g/dl at 40 weeks' gestation and one standard deviation is approximately 1 g/dl. The haemoglobin was also measured in fetal blood from 154 red cell isoimmunised pregnancies from 17 to 36 weeks' gestation.
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. The normal ranges are: Newborns: 17-22 gm/dL. One (1) week of age: 15-20 gm/dL. One (1) month of age: 11-15gm/dL. Children: 11-13 gm/dL. Adult males: 14-18 gm/dL. Adult women: 12-16 gm/dL. Men after middle age: 12.4-14.9 gm/dL.
