The direct bilirubin test measures the level of conjugated bilirubin in the blood. Conjugated bilirubin is bilirubin that has been processed by the liver and is water-soluble. Elevated direct bilirubin levels can indicate liver dysfunction, bile duct obstruction, or hepatobiliary disease. This test is used to diagnose and monitor liver diseases, such as hepatitis, cirrhosis, and gallstones. It helps differentiate between different types of jaundice and provides valuable information for guiding treatment decisions. The direct bilirubin test is often performed alongside the total bilirubin test for a comprehensive evaluation of liver function.
