What is this test?

This test checks a 24-hour urine collection for the presence of bilirubin, a yellow pigment made during the breakdown of red blood cells. The strip provides a qualitative result, such as negative or positive, rather than an exact measurement.

Why might I need this test?

A clinician may order this test as part of an evaluation for jaundice, liver disease, bile duct problems, or increased red blood cell breakdown. It may be used with other urine and blood tests to help determine the cause of an abnormal result.

How is the test performed?

You collect all urine for a full 24-hour period in the container provided by the laboratory. A laboratory staff member may dip a bilirubin reagent strip into the collected urine and compare the color change with the strip's reference chart.

How do I prepare for the test?

Follow the laboratory's instructions for the 24-hour collection, including when to begin and end it and how to store the container. Do not change your diet, medications, or fluid intake unless your clinician specifically instructs you to do so.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Bilirubin is normally not detectable in urine. A positive result may occur when the body is producing and excreting increased amounts of bilirubin, which can be associated with liver or bile duct disease or increased red blood cell breakdown. Results can also be affected by collection or testing conditions, so the result should be interpreted by a clinician using your medical history and other laboratory findings.

Frequently asked questions

Does a positive result always mean I have a liver disease?
No. It may suggest increased bilirubin production or impaired processing and excretion, but it does not identify a specific condition by itself. Your clinician will interpret it alongside other tests.
Why is a 24-hour urine collection required?
Collecting all urine for 24 hours provides a more complete representation of what your body is excreting than a single urine sample. It also helps reduce variability caused by urine concentration.
Can medications or urine color affect the result?
Some medications and conditions that darken the urine can affect interpretation of a dipstick color change. Tell the laboratory and your clinician about medications, recent vitamin use, and any changes in urine color.
