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.
This molecule carries oxygen from the lungs to the different parts of the body. A normal hemoglobin level is at 13.8 to 17.2 gm/dL of blood for males and 12.1 to 15.1 gm/dL of blood for females. Normal limits for children vary with their sex and age. A low hemoglobin count is commonly seen in routine blood tests.For males, it is below 13.5 gm/dL, and for females, it is below 12 gm/dl. Blood test-A routine blood test will show if you have a low hemoglobin count. 2  The underlying cause of anemia, if present, will be shown by doing a complete medical history, physical examination and other laboratory blood tests.
