Bilirubin is a breakdown product of hemoglobin, and elevated levels, particularly conjugated bilirubin, can indicate liver disease or cholestatic processes.

“Billy Rubin is a breakdown product of hemoglobin and comes in two types generally it's not measured or fractionated into direct and indirect on the comprehensive metabolic panel mine just is total my total was 0.7 milligrams per deciliter but direct bilirubin is also called conjugated bilirubin in the liver the body will take unconjugated bilirubin and conjugate it to a glucuronidase gaited bilirubin which makes it water-soluble and it goes out in the bile and can go out in the urine as well but it should not spill over into the urine unconjugated bilirubin is something that we should not see elevated there are a number of differential diagnoses here if you see a elevated unconjugated bilirubin generally you think of either hemolysis or which is a genetic polymorphism in the enzyme which does the glucuronidation of bilirubin in the liver”
