What is this test?

This test measures the concentration of bilirubin in a patient sample. Bilirubin is a yellow pigment formed when the body breaks down hemoglobin from aging red blood cells.

Why might I need this test?

A bilirubin test may be ordered to help evaluate jaundice, which can cause yellowing of the skin or whites of the eyes. It may also be used when monitoring liver disease or investigating unexplained changes in blood-cell counts.

How is the test performed?

A prepared sample is applied to a reagent strip, and an automated instrument analyzes the color change to estimate the bilirubin concentration. The specimen type is not specified in the abbreviated test name.

How do I prepare for the test?

Follow the laboratory's instructions for collecting and submitting the sample. Fasting is generally not required unless your healthcare professional specifically tells you to fast.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

An elevated bilirubin concentration may result from increased red blood cell breakdown, liver inflammation, or impaired bile flow. Mild increases can also occur with conditions such as Gilbert syndrome. Results should be interpreted with other liver tests and your clinical history because interpretation varies by specimen.

Short name

Automated Bilirubin Strip

Frequently asked questions

What does bilirubin measure?
The test estimates the amount of bilirubin in a sample. Bilirubin is produced during the breakdown of red blood cells and is normally processed by the liver.
Why does an elevated bilirubin level matter?
A higher level may be associated with blood-cell breakdown, liver disease, or blocked bile flow. It can also contribute to jaundice and may be seen with Gilbert syndrome.
Does this test require fasting?
Fasting is usually not required. Follow any specific preparation instructions provided by the laboratory or your healthcare professional.
