What Causes High Bilirubin Levels?

Bilirubin blood levels that are higher than normal may be caused by issues affecting the liver or bile ducts.  If the liver is not functioning normally, it may be unable to process bilirubin efficiently.  Blockages in the bile ducts can cause bilirubin to leak into the bloodstream.  It may also indicate that your red blood cells are being destroyed at an increased rate, which is often caused by hemolytic anemia.

How it Works

What is Bilirubin?

Bilirubin is a waste product that is produced during the breakdown of old red blood cells.  Bilirubin passes through the liver on its way to be removed from the body.  Bile, which is removed through the intestines, is made of bilirubin and other waste products filtered by the liver.

Why is a bilirubin blood test ordered?

Bilirubin is usually measured as part of testing to assess liver function.  When someone has symptoms of liver disease, such as jaundice (yellowing of the skin or eyes), a hepatic function blood test can be performed.  This testing measures bilirubin and other liver enzymes.  Testing can also be done to investigate the cause of anemia or to monitor treatment for liver disease.  Bilirubin and liver function testing are also included in common general health tests like a comprehensive metabolic panel. 

What is the difference between total and direct bilirubin?

Some bilirubin tests distinguish between the total amount of bilirubin and the direct bilirubin.  Before passing through the liver, bilirubin is bound to proteins.  Bilirubin that has been processed by the liver is referred to as direct bilirubin.  Measuring both the total and direct bilirubin levels can help to determine what type of health issue may be causing your bilirubin levels to rise.
