Question
When the baby was 3 months old, the alanine aminotransferase level measured was 66.2, with the normal range being 0 to 40. What should be done? Both parents have no history of liver disease.
Answer
Jaundice in newborns is a common occurrence, caused by the unique bilirubin metabolism of newborns. Most full-term babies will develop jaundice within 3 to 5 days after birth, which usually resolves naturally within 14 days. However, if jaundice persists for an extended period (more than 2 weeks for full-term infants, more than 4 weeks for preterm infants) or recurs after jaundice has subsided, this may be a sign of pathological jaundice. Pathological jaundice can be associated with various factors, including infections and hemolytic diseases, and further examination and treatment may be required. The doctor should assess the baby’s condition and determine if treatment or further investigation is necessary.
