What Does Low Total Bilirubin Mean
Bilirubin, a product of hemoglobin breakdown, is present in two forms in the human body: unconjugated (indirect bilirubin, insoluble) and conjugated (direct bilirubin, soluble). Unconjugated bilirubin is conjugated in the liver and released into the small intestine in bile, the fluid in the gallbladder. Total bilirubin measures indirect bilirubin plus direct bilirubin; part of ...Read more

Bilirubin is the potentially toxic product of heme metabolism. It is formed by breakdown of heme present in hemoglobin, myoglobin, cytochromes, catalase, peroxidase and tryptophan pyrrolase. Eighty percent of the daily bilirubin production comes from hemoglobin. It requires conversion to a water-soluble form before elimination from the body by ...Read more
