What is this test?

Bilirubin is a yellow pigment made when the body breaks down old red blood cells. A qualitative bilirubin test reports whether bilirubin is detected in the specimen.

Why might I need this test?

This test may be used to evaluate jaundice, unexplained yellowing of the skin or eyes, symptoms of liver disease, or suspected problems with bile drainage.

How is the test performed?

A laboratory professional collects a small specimen and uses a validated method to determine whether bilirubin is present. The specimen and testing method may vary based on the clinical situation.

How do I prepare for the test?

Special preparation is often unnecessary, but you should follow any instructions from your healthcare professional. Tell the laboratory if you are pregnant or have recently taken a medication that could affect the result.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

What does a qualitative bilirubin result mean?
It indicates whether bilirubin was detected in the specimen. It does not provide the same precise concentration information as a quantitative bilirubin test.
Why is bilirubin checked?
Bilirubin is commonly checked when jaundice is present or when a liver, gallbladder, bile duct, or blood-cell problem is suspected.
Does a detected bilirubin level always mean there is a serious problem?
No. Bilirubin can be detectable for different reasons, and the result must be considered with the specimen type, symptoms, medical history, and other tests.
