Overview
Jaundice is classified in two categories: Unconjugated hyperbilirubinemia and combined conjugated and unconjugated hyperbilirubinema. Unconjugated hypebilirubinemia can be caused by eiether increased production, reduced reuptake or defects in conjugation. While combined conjugated and unconjugated hyperbilirubinemia is further classified into: Obstruction of biliary tract, Interahepatic cholestasis, injury to hepatocellular parenchyma and defects of hepatocellular canalicular excretion or re-uptake in sinusoids
