For the quantitative determination of in Bilirubin (Direct) in serum. For IN VITRO diagnostic use.
Bilirubin is a product of hemoglobin breakdown by the reticuloendothelial system and exists in two forms. Unconjugated (indirect) bilirubin is transported to the liver bound by albumin where it becomes conjugated (direct) with glucuronic acid and excreted.
Elevated serum bilirubin is indicative of impairment of the liver, excessive hemolysis, or obstruction of the biliary tract.
Bilirubin determination is generally based on the reaction of bilirubin with diazotized sulfanilic acid, as described by Ehrlich (1). In this method, direct (conjugated) bilirubin couples with a diazonium salt in the presence of sulfamic acid to form the colored compound, azo-bilirubin.
