Overview
The Bilirubin (Total, Direct & Indirect) Serum test measures the levels of bilirubin in the blood. Bilirubin is a yellow pigment produced when red blood cells break down. The liver processes bilirubin and helps remove it from the body through bile. This test includes Total Bilirubin, Direct Bilirubin, and Indirect Bilirubin measurements, helping healthcare providers assess liver function, bile duct health, and conditions related to excessive red blood cell destruction.
What It Measures
Total Bilirubin: The overall amount of bilirubin in the blood.
Direct (Conjugated) Bilirubin: Bilirubin processed by the liver and ready for excretion.
Indirect (Unconjugated) Bilirubin: Bilirubin that has not yet been processed by the liver.
Why Take This Test?
- To evaluate liver function and liver diseases. To investigate jaundice (yellowing of the skin and eyes). To assess bile duct obstruction. To monitor hepatitis
- cirrhosis
- and other liver conditions. To evaluate excessive red blood cell breakdown (hemolysis).
