Does high bilirubin affect urine?

If there is too much bilirubin in your blood, it can cause health problems. Bilirubin can also come out in the urine, causing it to look very dark.

What can elevate a patient’s urobilinogen level?

Elevated levels may indicate hemolytic anaemia (excessive breakdown of red blood cells RBC), overburdening of the liver, increased urobilinogen production, re-absorption – a large hematoma, restricted liver function, hepatic infection, poisoning or liver cirrhosis.

What happens to urobilinogen in liver?

Most of the urobilinogen is excreted in the feces, but some is reabsorbed into the blood and goes either into the liver for reexcretion in the bile, or the urine. In patients with complete bile duct obstruction, no urobilinogen is formed.

Does a positive test for bilirubin indicate the presence of urobilinogen in urine?

Urinary urobilinogen may be increased in the presence of a hemolytic process such as hemolytic anemia. It may also be increased with infectious hepatitis, or with cirrhosis….Clinical Significance of Urobilinogen in Urine.

Condition Urine Bilirubin Result Urine Urobilinogen Result
Hepatitic disease Positive or negative Increased
Biliary obstruction Positive Normal*

How much urobilinogen is normal in urine?

The normal urobilinogen concentration in urine ranges from 0.1-1.8 mg/dl (1.7-30 µmol/l), concentrations >2.0 mg/dl (34 µmol/l) are considered to be pathological. Urobilinogen does not occur in urine, unless bilirubin gets into the intestines.

What does urobilinogen 2.0 mean?

Clinical Significance Urobilinogen is normally present in urine at concentrations up to 1.0 mg/dL. A result of 2.0 mg/dL represents the transition from normal to abnormal, and the patient and/or urine specimen should be evaluated further for hemolytic and hepatitis disease.
