Patient's question:
What are the index ranges for physiological jaundice and pathological jaundice in newborns? What is the highest jaundice index in newborns?Doctor's answer:
In clinical diagnosis, it is considered hyperbilirubinemia if the total bilirubin level in full-term infants is below 205.2 μmol/L (12 mg/dL) and in preterm infants is below 256.5 μmol/L (15 mg/dL). Physiological jaundice typically reappears 2 to 3 days after birth and usually subsides within 7 to 14 days. Pathological jaundice generally reappears shortly after birth or within 5 days after birth and requires phototherapy.
