How Does Hemolysis Affect Bilirubin?

Summary. In the van den Bergh reaction, hemolysis in serum samples results in decreased azobilirubin color development and hence in measured bilirubin levels which are falsely low.

Can hemolysis cause high bilirubin?

In hemolysis, the concentration of unconjugated bilirubin (indirect bilirubin) is increased, while in liver disease the level of conjugated bilirubin (direct bilirubin) is increased.

Why does hemolysis increase bilirubin?

Thus, extravascular hemolysis will result in increased presentation of unconjugated bilirubin to the hepatocyte. If the ability of the hepatocyte to take up and conjugate this bilirubin is overwhelmed, unconjugated bilirubin will accumulate in plasma, causing an increase in total and indirect bilirubin.
