Bilirubin in Urine
Reviewed
A bilirubin in urine test measures the levels of bilirubin in your urine. Normally, bilirubin isn't found in urine. If there is bilirubin in your urine (called bilirubinuria), it may be an early sign of a liver condition.
Preparation and collection
You don't need any special preparations for a bilirubin in urine test. If your provider has ordered other urine or blood tests, you may need to fast (not eat or drink) for several hours before the test. Certain medicines and supplements may affect your results, so let your provider know what you are taking. But don't stop taking any medicines unless your provider tells you to.
Understanding this test
Use the reference interval and units printed by the laboratory that performed the test. A result outside that interval is not a diagnosis by itself, and a result inside it does not rule out every condition. Your symptoms, history, medicines, timing, and related tests can change what the result means.
- A bilirubin in urine test is only one measure of your liver health.
- Certain medicines and supplements may affect your results, so let your provider know what you are taking.
What to do next
If your test results aren't normal, your provider may order other tests, including a liver panel. If you did an at-home bilirubin in urine test, talk with your provider about your results.
