Neonatal jaundice may indicate cholestasis rather than a benign, physiological condition. Any four-week-old newborn with persistent jaundice should have a fractionated bilirubin screen to determine whether the hyperbilirubinemia is unconjugated. Conjugated hyperbilirubinemia, a hallmark of neonatal cholestasis, is pathological and requires further investigation. These infants need prompt diagnosis, early intervention ...
