Test Code

The Bilirubin (Direct) test estimates the level of conjugated (water-soluble) bilirubin present in the bloodstream. Direct bilirubin is formed in the liver when unconjugated bilirubin is processed and made ready for excretion through bile into the intestines.
Elevated direct bilirubin levels typically indicate hepatic or post-hepatic causes such as liver cell injury, bile duct obstruction, hepatitis, cirrhosis, gallstones, or cholestasis.
This test is usually interpreted along with Total and Indirect Bilirubin, liver enzymes (ALT, AST, ALP), and clinical findings to determine the exact cause of jaundice or liver dysfunction.
