Bilirubin - urine

Bilirubin is a yellowish pigment found in bile, which is a fluid produced by the liver and stored in the gallbladder.

This article is about a lab test to measure the amount of bilirubin in the urine. Large amounts of bilirubin in the body can lead to jaundice.

Bilirubin may also be measured with a blood test.

How the Test is Performed

This test can be done on any urine sample.

For an infant, thoroughly wash the area where urine exits the body.

• Open a urine collection bag (a plastic bag with an adhesive paper on one end).
• For males, place the entire penis in the bag and attach the adhesive to the skin.
• For females, place the bag over the labia.
• Diaper as usual over the secured bag.

This procedure may take a few tries. An active baby can move the bag, causing urine to go into the diaper.

Check the infant often and change the bag after the infant has urinated into it. Drain the urine from the bag into the container provided by your health care provider.

Deliver the sample to the laboratory or to your provider as soon as possible.

How to Prepare for the Test

Many medicines can interfere with blood test results.

• Your provider will tell you if you need to stop taking any medicines before you have this test.
• Do not stop or change your medicines without first talking to your provider.
