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.
However, the National Institutes of Health offers the following general, accepted range for normal hemoglobin levels in children and adults: Normal range for adults: Male: 13.8 to 17.2 grams per deciliter (g/dL). Female: 12.1 to 15.1 g/dL.Normal range for children: Newborn: 14 to 24 g/dL. Infant: 9.5 to 13 g/dL. The normal hemoglobin levels for adults according to Mayo Clinic are similar, with the ranges slightly broader by a few points.For children, the ranges vary with age and sex. Hemoglobin transports oxygen from the lungs into the bodyâs cells and transports carbon dioxide out.ormal range for children: Newborn: 14 to 24 g/dL. Infant: 9.5 to 13 g/dL.
