When both total and direct bilirubin are tested, it can help to discern between different types of liver diseases.  

This test may be ordered if symptoms of liver disease are present such as:

  • jaundice
  • nausea
  • abdominal pain
  • fatigue
  • dark colored urine  

The components of this test are:

  • Total bilirubin- made up of direct and indirect form of the substance
  • Indirect bilirubin (also called Unconjugated) —when heme is released from hemoglobin, it is converted to unconjugated bilirubin. It is carried by proteins to the liver. Small amounts may be present in the blood.
  • Direct bilirubin (also called conjugated)—formed in the liver when sugars are attached (conjugated) to bilirubin. It enters the bile and passes from the liver to the small intestines and is eventually eliminated in the stool. Normally, no conjugated bilirubin is present in the blood.
