Studies on maturity in newborn infants. VII. Foetal haemoglobin.
Cord blood from 125 newborns of various gestational ages has been analysed for the ratio foetal haemoglobin to total haemoglobin, using an alkali denaturation method. The quotient, percentage of foetal haemoglobin divided by birth weight correlates well with gestational age. Thus the percentage of foetal haemoglobin in cord blood can be used as a method for estimating maturity in newborn infants. Foetal haemoglobin has been compared with other methods for maturity assessments and seems to give the same precision in estimating gestational age as the best of these, which is the scoring of external characteristics. However, the latter method is considerably less time-consuming and more suitable for routine use.
