What is this test?

This test uses a chemical reagent strip to detect bilirubin, a yellow pigment made when the body breaks down red blood cells. The sample type is not identified in the test code, so confirm whether urine, blood, or another specimen is being tested.

Why might I need this test?

Clinicians may use this test to evaluate jaundice, liver disease, or possible blockage of bile flow. It may also be used to monitor a person with an existing liver or gallbladder condition.

How is the test performed?

A laboratory technician applies the patient sample to the reagent strip. A chemical pad changes color, and the strip is compared with a color chart or read by an instrument to determine the bilirubin result.

How do I prepare for the test?

Preparation depends on the specimen ordered. Follow the laboratory's collection instructions, provide a fresh sample in the correct container, and tell the clinician about medicines, pregnancy, recent surgery, or a history of liver disease.

Frequently asked questions

What does the bilirubin test measure?
It measures the presence or concentration of bilirubin in the specimen. Bilirubin is a yellow pigment produced during the breakdown of red blood cells.
Does an elevated bilirubin level always mean I have liver disease?
No. Elevated bilirubin can also result from blood-cell breakdown, fasting, certain medicines, or blockage of bile flow. Your clinician will interpret it alongside your symptoms and other tests.
Do I need to fast before this test?
Fasting is not always required, and preparation can vary by specimen and laboratory. Follow the instructions on your test order and ask the laboratory if you are unsure.
