Bilirubin levels are usually the highest when the baby is 3 to 5 days old. At a minimum, babies should be checked for jaundice every 8 to 12 hours in the first 48 hours of life and again before 5 days of age.
Jaundice is a yellow discoloration of the skin and/or whites of the eyes that is often seen in newborn infants. The discoloration is caused by a yellow substance called bilirubin. Infants with high blood levels of bilirubin, called hyperbilirubinemia, develop the yellow color when bilirubin accumulates in the skin. Infants with darker skin color can have high blood bilirubin levels, and the jaundice may not be identified.
