| indirect reacting bilirubin | The fraction of serum bilirubin which has not been conjugated with glucuronic acid in the liver cell; so called because it reacts with the Ehrlich diazo reagent only when alcohol is added; increased levels are found in hepatic disease and haemolytic conditions. Synonym: unconjugated bilirubin. (05 Mar 2000) |
