How much jaundice is normal for a newborn at one month?

Patient's question:

No

Doctor's answer:

The normal value of neonatal jaundice is based on the reference index of serum bilirubin. As long as full-term infants do not exceed 204 μmol/L (12 mg/dL) and preterm infants do not exceed 255 μmol/L (15 mg/dL), it is considered normal.
Additionally, children with physiological jaundice, apart from the yellowing of the skin, do not have significant effects on appetite or mental state, and the symptoms usually resolve on their own within one month.
Children with pathological jaundice not only exhibit skin changes but also often cry, fuss, and refuse to feed. In such cases, parents must take their child to the hospital for treatment as soon as possible, as this may lead to kernicterus, which has very serious consequences.
