How to distinguish physiological jaundice from pathological jaundice

Patient's question:

Baby is six days old, jaundice level is 13.7. How to determine between physiological jaundice and pathological jaundice? On the third day of birth, jaundice was 8; on the fourth day, it was 9; on the fifth day, it was 11.7; and on the sixth day, it was 13.7. The baby is breastfed, can eat and sleep well, and has also been given sugar water to drink.

Doctor's answer:

Hello, the baby's jaundice index is gradually increasing, and the total jaundice index has already exceeded the upper limit of physiological jaundice. The characteristics of physiological jaundice are that it appears 2 to 3 days after birth in full-term infants, reaches its peak on days 4 to 5, and disappears between days 5 to 7, with the latest not exceeding two weeks. In premature infants, jaundice often occurs 3 to 5 days after birth, reaches its peak on days 5 to 7, and disappears between days 7 to 9, with the latest not exceeding 3 to 4 weeks. The characteristics of pathological jaundice are that jaundice appears within 24 hours after birth; jaundice persists for a long time, and after jaundice has subsided, it reappears.
