Urobilinogen Bilirubin, Urine


A healthy result should fall into the range 0.2 - 1 mg/dL.

Urobilinogen is normally present in the urine in low concentrations (0.2-1.0 mg/dL).

How is it formed?

It is formed from bilirubin by intestinal bacteria in the duodenum, and a portion of it is absorbed back into the blood. Most urobilinogen is excreted in the feces or transported back to the liver and converted into bile. The remaining urobilinogen (<1%) is excreted in the urine.
