Unconjugated (indirect) bilirubin is the difference between total and direct bilirubin. Unconjugated (indirect) bilirubin in serum is bound to albumin. Elevated levels may indicate liver damage or disease. Higher than normal levels of direct bilirubin in your blood may indicate your liver isn't clearing bilirubin properly. Elevated levels of indirect bilirubin may indicate other problems.
Normal ranges of indirect bilirubin: 0.2-0.8 mg/dL or 3.4-12.0 μmol/L (SI units)
What is a high level of unconjugated bilirubin?
In patients, when the serum total bilirubin levels exceed 3.0 mg/dL, jaundice becomes clinically apparent. The hyperbilirubinemia is unconjugated when the conjugated bilirubin level is less than 15% of the TB.
How do you reduce indirect bilirubin?
Following these four tips can help you boost overall liver health in addition to medical guidance. Stay hydrated. Staying hydrated helps lower bilirubin levels by facilitating the removal of waste from the body. Consume fresh fruits and vegetables. Increase your intake of fiber. Avoid alcohol.
