Serum cord total bilirubin levels can define a subgroup of infants who are at a higher risk for developing significant hyperbilirubinemia and requiring phototherapy. Infants with cord bilirubin levels less than 2.0 mg/dL have only a 4 percent chance of developing hyperbilirubinemia and a 1.4 percent chance of needing phototherapy. However, if serum cord bilirubin levels are more than 2.0 mg/dL, the infant has a 25 percent chance of developing subsequent hyperbilirubinemia. With early discharge from the nursery a more common practice, this level can identify at an early age those infants who need closer follow-up.
血清脐带总胆红素水平可确定一组发生显著高胆红素血症并需要光疗风险较高的婴儿。脐带胆红素水平低于2.0mg/dL的婴儿发生高胆红素血症的几率仅为4%，需要光疗的几率为1.4%。然而，如果血清脐带胆红素水平超过2.0mg/dL，婴儿随后发生高胆红素血症的几率为25%。随着从托儿所提前出院这种做法越来越普遍，该水平可在早期识别出那些需要密切随访的婴儿。
