Bilirubin (Total, Direct and Indirect)
What is Bilirubin (Total, Direct and Indirect)?
It is usually ordered when you have signs or symptoms of liver damage, liver disease like jaundice, dark urine, nausea, vomiting; when you have evidence of bile duct blockage or hemolytic anemia. Sometimes, it is also ordered in newborns with jaundice.
Why is Bilirubin (Total, Direct and Indirect) done?
- If you have signs or symptoms of liver disease like dark colored urine, jaundice, nausea, vomiting, abdominal pain, fatigue
- As a part of liver function test or routine health check up
- If you have a history of taking excess amounts of alcohol
- If you have been exposed to hepatitis causing virus
- If you have symptoms or signs of hemolytic anemia like pale skin, jaundice, splenomegaly
- In newborns, to monitor neonatal jaundice
Interpreting Bilirubin (Total, Direct and Indirect) results
- Increased total bilirubin which is mainly unconjugated may be due to hemolytic anemia, transfusion reactions
- Increased total bilirubin which is mainly conjugated may be due to viral hepatitis, drug reactions, alcoholic liver disease, gall stones or any obstruction in the bile ducts
- Low levels of bilirubin are usually not a cause for concern and therefore not monitored
