Urinary bile

Urine biliary test is an auxiliary test method to check whether urine is normal. Urine bile pigments include bilirubin, urobilinogen, and urobilin, commonly known as urinary tribiliary. Because most of the submitted urine is fresh urine, urobilinogen has not been oxidized into urobilin, and the first two are commonly referred to as urinary bile. Through this examination, the corresponding symptoms can be judged.
