Bilirubin is a product of the breakdown of hemoglobin from old red blood cells. It is transported to the liver, converted into a water-soluble form, and excreted in bile. Total bilirubin testing is used to diagnose and monitor liver diseases, bile duct obstruction, hemolytic anemia, and jaundice. Elevated total bilirubin may indicate liver problems or bile duct obstruction, while low levels are rare and usually clinically insignificant.
Total bilirubin is a compound produced from the breakdown of red blood cells and is measured to assess liver and bile duct health.
