BIL-T | Total bilirubin

Total bilirubin (BIL-T) - direct bilirubin (conjugated) + indirect bilirubin (unconjugated). Bilirubin is one of the components of bile. It is produced in the liver, spleen and bone marrow. Bilirubin is also produced during the breakdown of erythrocytes. Total bilirubin increases with hemolysis, gallstone disease, mechanical jaundice, vitamin B12 deficiency anemia, Gilbert's disease, Dubin-Johnsin syndrome, Crigler-Najjar syndrome. Total and direct bilirubin should be determined for differential diagnosis of liver diseases. In addition, additional laboratory indicators greatly expand the possibilities of interpreting the bilirubin test.
