The urobilinogen test is used to determine the urobilinogen amount in your urine sample. Urobilinogen is formed due to decrease in bilirubin levels. Bilirubin is a yellowish substance that is found in the liver and assists in breaking red blood cells. A normal person's urine has a particular amount of urobilinogen, but if the amount is little or next to none, this is sign that your liver is not functioning properly. If the urobilinogen amount is too high, this can mean patient is suffering from liver disease like cirrhosis or hepatitis. Urinary urobilinogen is known to increase during the hemolytic process like hemolytic anemia. Comparison of the urinary bilirubin result with the urobilinogen result can help in identifying biliary obstruction, hepatic disease and red cell hemolysis. This test is also known as a urine test, UA, chemical urinalysis and urine analysis.
