The Jaundice 30-day Comparison Chart is used as a reference to determine whether a baby’s jaundice index is normal or not within 30 days from birth. There are two types of jaundice: physiologic and pathologic. Parents can also judge the appearance and receding time of their baby’s jaundice according to the 30-day comparison table to determine whether the type of jaundice is normal or not. Physiologic jaundice starts to appear 2~3 days after birth, and lasts no more than 2 weeks for full-term babies and 3~4 weeks for premature babies. Jaundice will fade away automatically as the baby grows up and will not reappear. Pathologic jaundice usually appears within 24 hours after birth and lasts longer, lasting more than 2 weeks in full-term babies and more than 4 weeks in premature babies. Pathological jaundice will not disappear on its own and requires early intervention and prompt treatment under the guidance of a doctor. Consult your doctor for the specifics of your baby’s jaundice to avoid delays in treatment.
