Frequently Asked Questions
Is fasting required for Bilirubin Total test?
Fasting is not strictly required for total bilirubin, but it is often recommended along with other liver function tests to avoid lipemic interference with the diazo method.
What is the normal range for total bilirubin?
The normal reference range for total bilirubin in adults is typically 0.2 to 1.2 mg/dL (3.4 to 20.5 µmol/L), though laboratories may have slight variations.
What does elevated total bilirubin indicate?
High total bilirubin may suggest hemolysis, liver dysfunction such as hepatitis or cirrhosis, or biliary obstruction. It is commonly associated with jaundice, yellowing of skin and eyes.
How are results interpreted?
Results are interpreted alongside direct and indirect bilirubin fractions, liver enzymes (ALT, AST, ALP), and clinical context to determine whether elevation is pre-hepatic, hepatic, or post-hepatic.
Can medications affect bilirubin levels?
Yes, certain drugs like rifampicin, azathioprine, and some antibiotics can elevate bilirubin. Inform your doctor about all medications before testing.
