What is this test?

This test measures the presence and overall level of bilirubin in a blood sample. Bilirubin is a yellow pigment formed when the body breaks down old red blood cells.

Why might I need this test?

Your clinician may order this test to help investigate yellowing of the skin or eyes, changes in urine or stool color, liver symptoms, or unexplained red blood cell breakdown.

How is the test performed?

A small blood sample is collected and analyzed in the laboratory. This qualitative version reports a screening or presence result rather than providing a measured bilirubin concentration.

How do I prepare for the test?

Fasting is usually not required for this test, but your clinician may give specific instructions. Tell the care team about medicines, recent blood transfusions, or a history of liver or blood disorders.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

An abnormal result may occur with liver inflammation or dysfunction, obstruction of bile flow, or increased breakdown of red blood cells. The result is interpreted along with symptoms and other laboratory tests, so an abnormal finding does not identify one specific condition by itself.

Short name

Total bilirubin

Frequently asked questions

What does total bilirubin measure?
It evaluates bilirubin in the blood, including bilirubin that is not bound to a protein. Bilirubin is produced mainly as old red blood cells are broken down.
Why does bilirubin matter?
Bilirubin helps assess how the liver and red blood cells are working. Elevated levels can contribute to jaundice and may be associated with liver disease, bile duct blockage, or blood-cell breakdown.
Is this the same as a quantitative bilirubin test?
No. A qualitative result provides a screening or presence finding, while a quantitative test gives a numeric concentration. Your clinician may order both or another liver test for more complete evaluation.
