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.
A small amount of older red blood cells are replaced by new blood cells every day. Bilirubin is left after these older blood cells are removed. The liver helps break down bilirubin so that it can be removed from the body in the stool. A high level of bilirubin in the blood can lead to jaundice. Jaundice is a yellow color in the skin, mucus membranes, or eyes. Jaundice is the most common reason to check bilirubin level.
