Bilirubin (Total, Direct, Indirect)

Bilirubin is a yellowish waste product of red cell breakdown in the blood. It goes into the liver to be excreted out. High levels in the blood indicate inability of the liver to excrete bilirubin leading to jaundice. Direct bilirubin is the product that undergoes a chemical change in the liver, goes to intestines & is excreted in the stool. Indirect bilirubin is the product of red cell breakdown which goes to the liver.
