In this study we tested some factors associated with the prediction of hyperbilirubinemia of the newborn as cord, first day bilirubin blood levels, ABO, Rh incompatibility and use of oxytocin. This was conducted on 384 healthy term newborns, they were followed up for first 3 days of life. We analyzed bilirubin levels in cord blood and serum of the baby in first day . Any baby had total serum bilirubin (TSB) more than 17mg/dL considered as having significant hyperbilirubinemia.16.1% of included newborns developed significant hyperbiliruinemia. ROC curve analysis demonstrates that the cord blood bilirubin cut off point 2.38mg/dL, and first day bilirubin cut off point 5mg/dL .There was statistically significant relation between cord bilirubin level, first day bilirubin level and subsequent hyperbilirubinemia (P <0.01).We conclude that newborns having umbilical cord blood bilirubin level >2.38 mg/dL or first day (TSB)>5 mg/ dL should be followed up in the first 3 days of life.
