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.
Hemoglobin is a protein in red blood cells that carries oxygen. Normal values are 13.8 to 17.2 gm/dL for males and 12.1 to 15.1 for females. Low or high measures of hemoglobin are not good indications of either iron overload or iron deficiency.emoglobin is a protein in red blood cells that carries oxygen.
