Jaundice and Bilirubin
- Jaundice means the skin has turned yellow.
- Bilirubin is the pigment that turns the skin yellow.
- Bilirubin comes from the normal breakdown of old red blood cells.
- The liver normally gets rid of bilirubin. But, at birth, the liver may be immature.
- Half of babies have some jaundice. Usually it is mild.
- The level of bilirubin that is harmful is around 20. Reaching a level this high is rare.
- High levels need to be treated with bili-lights. That's why your doctor checks your baby's bilirubin levels until it becomes low.
