What is the cutoff level for neonatal bilirubin that serves to differentiate transient neonatal hyperbilirubinemia from potentially pathological hyperbilirubinemia during the first week of life of a full-term infant?

Hepatic capacity to conjugate bilirubin does not become fully mature until nearly 4 weeks postpartum in full-term human infants.This time is increased in preterm infants.Thus transient neonatal hyperbilirubinemia is frequently observed.Hyperbilirubinemia that does not surpass 12 mg/dL for a full-term infant and 15 mg/dL for a preterm infant is considered nonpathological.Higher bilirubin levels are typically associated with pathological causes.
