Bilirubin (bil-ih-ROO-bin) is a yellowish pigment that is made during the normal breakdown of red blood cells. Bilirubin passes through the liver and is eventually excreted out of the body. Higher than normal levels of bilirubin may indicate different types of liver or bile duct problems.

Is bilirubin found in blood?

Bilirubin in the bloodstream is usually in a free, or unconjugated, state; it is attached to albumin, a protein, as it is transported. Once in the liver it conjugates with glucuronic acid made from the sugar glucose. It is then concentrated to about 1,000 times the strength found in blood plasma.

How do you control bilirubin?

Can high bilirubin be cured?

There are no drugs to specifically treat increased bilirubin levels, unless there is an infection, blockage or tumor. Treatment is aimed at correcting the underlying cause of increased bilirubin levels, and minimizing further damage to your liver, if damage is present.
