Serum bilirubin concentration reflects the ability of hepatocytes to take up, conjugate and secrete bilirubin, so it is a functional marker rather than a marker of cellular integrity as reflected by serum transaminase levels. Pathologic elevation of conjugated bilirubin (concentration higher than 2 mg/dL or more than 20% of total bilirubin) is termed conjugated hyperbilirubinemia. It is a biochemical marker of cholestasis and hepatocellular dysfunction. Moreover, it may be observed in systemic illnesses with hepatic involvement. 


Serum bilirubin levels are used to rule out clinical conditions:

Pre-hepatic        -   Haemolytic crisis

Hepatic                 - Hepatic disease (decreased ability to conjugate and excrete bilirubin), intrahepatic cholestatic disease

Post-hepatic      -   Bile duct obstruction results in an accumulation of conjugated bilirubin.
