Bilirubin Blood Test - Normal Range

Bilirubin testing is usually done as part of a group of tests to check the health of your liver.  The test is to screen for or monitor liver disorders or hemolytic anemia, or to monitor newborn jaundice.

Test Preparation: may need to fast for several hours.

Normal Range:

Bilirubin test results are expressed as direct, indirect or total bilirubin. Total is a combination of direct and indirect bilirubin. Typically, you’ll get results for direct and total bilirubin.

  • Adults: <1.2 milligrams per deciliter (mg/dL) total bilirubin
  • Children(under 18): <1 mg/dL total bilirubin
  • Newborn: <0.3 mg/dL total bilirubin

Abnormal Result:

Lower than normal bilirubin levels are usually not a concern. Elevated levels may indicate liver damage or disease. Elevated levels of indirect bilirubin may indicate other problems.

Increased total bilirubin that is mainly indirect bilirubin may be a result of hemolytic or pernicious anemia, transfusion reaction, cirrhosis, Gilbert syndrome which is a relatively common inherited condition.
