Correlation of cord bilirubin levels with hyperbilirubinaemia in ABO incompatibility.

Abstract

We studied 91 offspring of ABO incompatible preganacies and 30 controls resulting from O--O pregnancies to test whether cord bilirubin levels could be used to predict the severity of hyperbilirubinaemia in ABO incompatibility. Blood group, direct Coombs's test, and serum bilirubin estimations were carried out on cord blood, and bilirubin estimations at 12, 24, 36, and 48 hours of life.
