A laboratory investigation into bilirubin binding in neonates

The presence of free bilirubin the serum of 59 Black neonates was studied at the time of exchange transfusion with an electrophoretic technique. It was observed that 32 infants had detectable free bilirubin in their serum and that these infants had a significantly greater bilirubin/albumin ratio that infants without free serum bilirubin.
