The Conjugated (D. Bilirubin) test is used to assess the functioning of the liver. It is a type of bilirubin test that measures the levels of direct or conjugated bilirubin in the blood. Bilirubin is a yellowish pigment that is produced when the red blood cells break down. It is processed by the liver and excreted out of the body through the bile.

Direct bilirubin is a form of bilirubin that has been processed by the liver and is ready to be excreted from the body. It is also known as conjugated bilirubin. Elevated levels of direct bilirubin in the blood indicate liver dysfunction, such as hepatitis or cirrhosis.

The Conjugated (D. Bilirubin) test is a part of the liver function test panel and is often performed along with other liver function tests, such as total bilirubin, indirect bilirubin, alkaline phosphatase, and AST/ALT. The test is also useful in monitoring the treatment of liver disorders and in assessing the liver damage caused by medications or alcohol.
