Urobilinogen (URO)

Urine bile pigments include bilirubin, urobilinogen, and urobilin, commonly known as urinary bilirubin. Because most of the tests are fresh urine, the urinary biliary has not been oxidized into urinary bilirubin, and the other two are commonly referred to as urinary biliary. The urinary bladder is converted into yellow urobilin (fecal bilirubin) by air oxidation and light irradiation.
