What is it used for?A bilirubin blood test is used to check the health of your liver. The test is also commonly used to help diagnose newborn jaundice. Many healthy babies get jaundice because their livers aren't mature enough to get rid of enough bilirubin. Newborn jaundice is usually harmless and clears up within a few weeks. But in some cases, high bilirubin levels can lead to brain damage, so infants are often tested as a precaution.
