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 Levels for Children. Children need optimal oxygenation for normal growth and development. According to the World Health Organization, a normal hemoglobin level for children age 6 months to 4 years is at or above 11 g/dL. A normal levels for children ages 5 to 12 years is at or above 11.5 g/dL.A normal level for adolescents ages 12 to 15 is at or above 12.0 g/dL.Any hemoglobin values below these cut-points can indicate anemia, a disorder characterized by a low red blood cell count, as well as low hemoglobin and hemocrit. normal level for a non-pregnant adult woman is between 12.1 and 15.1 g/dL. Men have higher hemoglobin levels than women because women lose red bloods each month during menstruation. A normal level for a pregnant woman is at or above 11.0 g/dL.
