Determinations of direct bilirubin (conjugated bilirubin) level in serum are mainly used in diagnosis of liver functions. Measurement of direct bilirubin concentration is used as an aid in diagnosis of clinical conditions associated with hyperbilirubinemia. Increased direct bilirubin levels can be observed in mechanical jaundice, Dubin-Jonson syndrome, bile ducts diseases, gallbladder diseases. Direct bilirubin is also the marker of perforation in acute sigmoid diverticulitis.
