Urobilinogen (urine)
Urobilinogen forms from bilirubin in the intestine; part of it returns to the blood and is excreted in the urine. Small amounts are normal; abnormalities may hint at the liver or breakdown of blood cells.
| Rating | Range | What it means |
|---|---|---|
| Good | below 20 µmol/L | Within range. |
| Worth improving | 20 µmol/L and above | Above the detection limit. As a test for liver disease this is outdated; assess with blood tests. |
Why it matters
ECLM: elevated with liver disease/hemolysis.
If it’s low
Absent urobilinogen (with jaundice) may indicate obstruction of the bile ducts — bilirubin does not reach the intestine.
If it’s high
Elevated urobilinogen can accompany liver disease or accelerated breakdown of blood cells (hemolysis).
What to do
Evaluate together with liver tests and bilirubin. On its own it is only a hint; an abnormality with jaundice belongs to a doctor.
When to see a doctor
An abnormality with jaundice, dark urine or pale stool → consultation
