Jaundice in the newborn or neonatal hyperbilirubinemia, is a common problem. Infants with persistent conjugated jaundice, lasting longer than 14 days of age in a term infant and 21 days in a preterm infant, should be referred to a national paediatric liver unit for investigation of the cause.

Investigations: 1. 90% of babies with prolonged jaundice are breast fed. Jaundice is clinically detectable in the newborn when the serum bilirubin levels are greater than 85 micromoles per litre.

In many cases this is a normal process and occurs in about 2/3 of all healthy newborns. This occurs in approximately 60% of term infants and 80% of preterm infants in the first week of life. The yellowish appearance is a sign of an increased blood pigment called Bilirubin, which then settles in the skin.
