Clinical Interest
Red blood cells at the end of their circulating lives are broken down in the reticuloendothelial system, mainly the spleen.
The resulting heme is converted to bilirubin upon removal of iron. This process accounts for about 80% of the 500 pmol (292 mg) of bilirubin formed daily. Once formed, bilirubin is transported to the liver bound to albumin. this fraction of bilirubin is referred to as indirect or unconjugated bilirubin.
Total bilirubin is the sum of the unconjugated and conjugated fractions. Total bilirubin is elevated in hepatitis, cirrhosis, hemolytic disorders, several inherited enzyme deficiencies, and conditions causing hepatic obstruction.
