A normal total bilirubin level for adults over 18 years old is up to 1.2 milligrams per deciliter (mg/dL) of blood. For individuals under 18, the normal range is 1 mg/dL. The normal level for conjugated (direct) bilirubin should be less than 0.3 mg/dL.
It's important to note that these are general guidelines, and individual levels may vary slightly depending on factors such as age, gender, and health status.
Newborn bilirubin levels are higher than in adults, with normal levels ranging between 1.0 and 12.0 mg/dL. This is because newborns' livers are still developing and may not be able to process bilirubin efficiently.
A bilirubin blood test can be used to measure bilirubin levels. High bilirubin levels can indicate problems with the liver or other organs. However, high bilirubin itself doesn't usually need treatment.
