It is Autosomal recessive disease characterized by Partial defect in excretion of conjugated bilirubin into the bile.

  1. Bilirubin: mild elevation of direct bilirubin
  2. Biopsy (dark pigment inside hepatocytes i.e the liver is black in colour), it had been proved to be a metabolite of catecholamines.
  3. +ve Bromosulphthalein (BSP) Test: Normally 90% of this dye is removed from blood within 45 minutes after I.V injection in normal liver.
  4. In Dubin-Johnson syndrome there is a late rise in plasma SSP after an initial fall due to reflux of the dye from the liver reflecting hepatic excretion defect.
