Details about Bilirubin (Urine)
What is the Bilirubin (Urine) Test?
The Bilirubin (Urine) test measures the presence of bilirubin in urine. Bilirubin is a yellow pigment produced during the normal breakdown of red blood cells and is processed by the liver before being excreted in bile.
Under normal conditions, bilirubin is not detectable in urine. Its presence usually indicates that conjugated bilirubin is entering the bloodstream due to impaired liver function or obstruction of bile flow. This makes urine bilirubin a useful early indicator of hepatobiliary disease.
The test is commonly included as part of urinalysis when liver or bile duct disease is suspected.
Why do I need a test for Urine Bilirubin?
You may need this test if there are signs or symptoms of liver dysfunction or bile duct obstruction. Because bilirubin can appear in urine before jaundice becomes clinically visible, this test can help detect problems early.
It is also used to investigate abnormal liver blood tests, unexplained dark urine or suspected hepatobiliary disease. The test helps differentiate liver-related causes of symptoms from other conditions.
Symptoms and scenarios where testing is recommended:
- Yellowing of skin or eyes (jaundice)
- Dark-coloured urine
- Pale stools
- Abdominal pain or discomfort
- Abnormal liver blood tests
- Suspected bile duct obstruction
- Liver disease monitoring
- Unexplained fatigue or nausea

Helps identify cholestatic conditions. - Non-invasive screening tool
Requires only a urine sample. - Supports liver disease investigation
Complements blood-based liver tests. - Useful in acute and chronic liver conditions
Helps monitor disease progression. - Quick and simple testing method
Results are rapidly available. - Aids differential diagnosis
Helps distinguish liver-related causes of symptoms. - Accessible and widely used test
Commonly included in routine urinalysis.

Your Results Explained
Negative Result
No bilirubin detected in urine.
This is a normal finding and suggests normal bilirubin metabolism and bile flow.
Trace / Low Levels
Small amounts of bilirubin may indicate early liver dysfunction.
Further blood testing is often recommended.
Positive Result
Detectable bilirubin suggests liver disease or bile duct obstruction.
Results are interpreted alongside liver blood tests and clinical findings.

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
