What is the normal indirect bilirubin value listed?

Normal indirect bilirubin reflects the unconjugated bilirubin circulating before the liver conjugates it. This fraction is typically in the range of about 0.2–0.8 mg/dL. A value of 0.5 mg/dL is well within that normal range, so it would be considered normal. Elevated indirect bilirubin suggests increased production or impaired conjugation (for example, hemolysis or Gilbert’s syndrome), while direct bilirubin rises point to conjugation or bile-flow issues. Total bilirubin equals the sum of direct and indirect.
