Common NameD-Urobilinogen
DescriptionUrobilinogen is a colourless product of bilirubin reduction. It is formed in the intestines by bacterial action. Some urobilinogen is reabsorbed, taken up by the hepatocytes into the circulation and excreted by the kidney. This constitutes the normal "intrahepatic urobilinogen cycle". Increased amounts of bilirubin are formed in haemolysis which generates increased urobilinogen in the gut. In liver disease (such as hepatitis) the intrahepatic urobilinogen cycle is inhibited also increasing urobilinogen levels. Urobilinogen is converted to the yellow pigmented urobilin apparent in urine. The urobilinogen remaining in the intestine (stercobilinogen) is oxidized to brown stercobilin which gives the feces their characteristic color. In biliary obstruction, below normal amounts of conjugated bilirubin reach the intestine for conversion to urobilinogen. With limited urobilinogen available for reabsorption and excretion, the amount of urobilin found in the urine is low.
