What is the normal jaundice level for a 5-day-old newborn?

Normal bilirubin levels for a 5-day-old newborn: 1. Normal range: At 5 days after birth, a newborn's serum bilirubin level should generally be less than 12 mg/dL. This range may vary slightly depending on the infant's birth weight, gestational age, and feeding status. A level higher than this may suggest jaundice. 2. Physiological vs. pathological jaundice: Physiological jaundice typically appears within a few days after birth and gradually resolves within two weeks. Pathological jaundice is characterized by higher bilirubin levels or prolonged duration, requiring further evaluation and treatment. 3. Monitoring of jaundice: Regular monitoring of bilirubin levels is important to assess the severity and progression of jaundice. Doctors will determine whether further tests or interventions are needed based on bilirubin levels and other related symptoms. If bilirubin levels are abnormal or jaundice persists, prompt medical attention is recommended.
