Normal range of jaundice at birth

jaundice is a common phenomenon in neonatal period, divided into physiological jaundice and pathological jaundice. In physiological jaundice, full-term babies show jaundice about 2-3 days after birth, peak at 4-5 days, begin to subside at 6-7 days, and completely subside within 2 weeks. Premature babies may last until 4 weeks. In addition, daily serum bilirubin elevation of less than 5mg/dL, serum bilirubin of less than 12mg/dL in term infants, and serum bilirubin of less than 15mg/dL in preterm infants are considered physiological jaundice, while pathological jaundice has higher bilirubin levels, exceeding 12mg/dL in term infants, and exceeding 15mg/dL in preterm infants. Not only that, bilirubin elevation is faster than 5mg/dL daily.
