Also known as: newborn jaundice · neonatal hyperbilirubinaemia
Yellow discolouration from raised bilirubin in a newborn — very common. Most is benign physiological jaundice, but pathological causes must be identified and treated to prevent kernicterus (bilirubin brain injury).
Nearly all newborns have some jaundice; it is higher or pathological with prematurity, blood-group incompatibility (Rh/ABO), G6PD deficiency, sepsis, bruising/cephalhaematoma and inadequate feeding.
Unconjugated hyperbilirubinaemia above threshold
