Bilirubin - Indirect (Unconjugated) Test

The Bilirubin - Indirect, Serum test measures the level of unconjugated (indirect) bilirubin in the blood. Bilirubin is a yellow pigment formed during the normal breakdown of red blood cells. This test helps evaluate liver function, red blood cell destruction, and conditions affecting bilirubin metabolism.

Why is this test done?

Doctors may recommend this test to:

• Assess liver health and liver function
• Diagnose jaundice and related disorders
• Detect hemolytic anemia (excess breakdown of red blood cells)
• Monitor liver diseases such as hepatitis or cirrhosis
• Evaluate newborn jaundice
• Identify inherited bilirubin metabolism disorders like Gilbert syndrome
