title: Accuracy of measurements of HbF with OSM3 in neonates and infants.
abstract: The accuracy of the Radiometer OSM3 oxymeter for measurement of fetal haemoglobin (HbF) in infants was investigated, and compared to one of the standard reference methods using alkali electrophoresis of haemoglobin. Blood samples of 37 infants with different gestational (27-41 weeks) and postnatal (1-198 days) ages were analysed. The two methods gave very close results but a significant mean difference (range -4.5-16.5%). However, agreement between the two methods was judged clinically acceptable (95% limits of agreement -7.5-15.5%). A rapid determination of HbF percentage, using OSM3, is an important determinant for correct assessment of oxygen saturation in newborn infants in intensive care units.
