What is this test?

This test measures the amount of bilirubin in venous whole blood. Bilirubin is a yellow pigment formed when the body breaks down heme, the iron-containing part of blood hemoglobin.

Why might I need this test?

A clinician may order this test to evaluate jaundice, changes in liver function, or suspected problems with bile drainage. It may also be used when there is concern that red blood cells are breaking down faster than normal.

How is the test performed?

A blood sample is collected from a vein in your arm. The laboratory measures bilirubin in the sample, usually using a chemical or automated laboratory method.

How do I prepare for the test?

Fasting is usually not required for this test, but your clinician may give specific instructions. Tell the laboratory if you are pregnant or may be pregnant, because pregnancy can affect bilirubin levels.

Frequently asked questions

What does a high bilirubin level mean?
A high level can indicate that red blood cells are breaking down rapidly, that the liver is not processing bilirubin normally, or that bile flow is blocked. Your clinician will interpret the result alongside your symptoms and other tests.
Does this test require fasting?
Fasting is usually not required, although it may be requested in some situations. Follow any preparation instructions provided by your clinician or laboratory.
What symptoms can accompany an abnormal result?
Elevated bilirubin may be associated with yellowing of the skin or eyes, dark urine, pale stools, fatigue, or abdominal discomfort. Some people have an abnormal result without noticeable symptoms.
