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 following listing shows the normal Hemoglobin ranges for each distinct age or sex group: Normal, High and Low Hemoglobin Levels. Newborn: the Normal Hemoglobin Level ranges between 14 and 24 g/dl. Newborn to 2 weeks: Hemoglobin Normal Ranges between 12 and 20 g/dl.2 to 6 months: Normal Hemoglobin Level Range is 10 to 17 g/dl. 6 to 12 months: Normal Hemoglobin Level ranges between 9.5 and 14 g/dl.1 to 6 years: 9.5 to 14 g/dl.6 to 18 years: 10 to 15.5 g/dl.he following listing shows the normal Hemoglobin ranges for each distinct age or sex group: Normal, High and Low Hemoglobin Levels. Newborn: the Normal Hemoglobin Level ranges between 14 and 24 g/dl. Newborn to 2 weeks: Hemoglobin Normal Ranges between 12 and 20 g/dl.
