Study Notes
Infection and Urobilinogen in Urine
- Cholangitis with obstruction leads to high urine urobilinogen and bilirubin excretion.
- High urine urobilinogen with absent bilirubin suggests hemolysis.
- Hemolysis, including acute erythrocyte lysis or bone marrow erythrocyte precursor destruction (megaloblastic anemias), increases urine urobilinogen.
- Bleeding into tissues and subsequent bilirubin excess also increases urinary urobilinogen.
Dark Stools and Urobilinogen
- High urobilinogen excretion also causes dark-colored stools.
Fever, Dehydration, and Urine Urobilinogen
- Fever with dehydration and concentrated urine can increase urinary urobilinogen.
