Urine Bilirubin
Understand Urine Bilirubin for liver function and bile flow assessment. Monitor hepatic health through urinalysis tracking.
What is Urine Bilirubin?
Urine bilirubin detects the presence of conjugated (water-soluble) bilirubin in urine. Normally, only trace amounts appear in urine, but when liver function is impaired or bile flow is blocked, excess conjugated bilirubin spills into the urine.
Why is it Tested?
Doctors test urine bilirubin to screen for liver disease, investigate jaundice causes, assess bile duct obstruction, and monitor liver function. It’s a sensitive early indicator of hepatic dysfunction, often becoming positive before jaundice is visible.
Normal Ranges
Normal urine bilirubin results:
- Normal: Negative or trace amounts
Any significant positive result warrants further investigation of liver function and bile flow.
Reference ranges vary by authority. Track yours across multiple standards with automatic unit conversions in LabsVault.
What do Abnormal Results Mean?
Abnormal results are not a diagnosis. Always discuss your results with a qualified healthcare provider before making any medical decisions.
Negative Urine Bilirubin
Normal finding indicating:
- Adequate liver function
- Unobstructed bile flow
- Normal bilirubin metabolism
Positive Urine Bilirubin
Presence in urine suggests:
- Hepatitis or liver disease
- Bile duct obstruction
- Cirrhosis
- Drug-induced liver injury
- Gallstones blocking bile flow
How to Track Over Time
Urine bilirubin serves as an early warning system for liver problems, often becoming positive before blood bilirubin rises significantly. Regular monitoring helps track liver disease progression and treatment response, with improving results indicating restored liver function or bile flow.
