Bilirubin is an orange-yellow pigment, a waste product primarily produced by the normal breakdown of heme, a component of hemoglobin.
Bilirubin is ultimately processed by the liver to allow its elimination from the body.
This test measures the amount of bilirubin in the blood to evaluate a person’s liver function so it is usually ordered in conjunction with other laboratory tests (alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase) when someone shows signs of abnormal liver function. It may also be ordered when there is evidence of jaundice, when an individual has a history of excessive alcohol consumption, if drug toxicity is suspected, or if a person has been exposed to hepatitis.
Measuring and monitoring bilirubin in newborns with jaundice is considered standard medical care.
