Contributor(s): Kathleen P Freeman

Overview

  • Formed in gut by bacterial reduction of bilirubin.
  • Small amount may be present in normal urine.
  • Used in humans for investigation of liver disease.
  • Not a useful test in small animals as the absence of urobilinogen (occurs with complete bile duct obstruction) cannot be determined.
