However, because there are many causes for hyperbilirubinemia, it is important to know which type of bilirubin is elevated -- the form that exists prior to conjugation by the liver, which is called indirect bilirubin, or the type that exists after conjugation by the liver, which is called the direct bilirubin. Approximately 250 mg of bilirubin per day is produced by an average adult through the catabolism of the heme molecule.4 Heme is released during red blood cell destruction. This content does not have an English version. Higher than usual levels of bilirubin may indicate different types of liver or bile duct problems. The initial laboratory evaluation should include fractionated bilirubin, a complete blood count, alanine transaminase, aspartate transaminase, alkaline phosphatase, -glutamyltransferase, prothrombin time and/or international normalized ratio, albumin, and protein.

INIS Repository Search provides online access to one of the world's largest collections on the peaceful uses of nuclear science and technology. This article updates a previous article on this topic by Roche and Kobos. It is first converted to biliverdin and then to unconjugated bilirubin within macrophages in the reticular endothelial system.5 Unconjugated bilirubin is lipid soluble and passes easily through cell membranes to bind to albumin in serum, whereas free (unbound) bilirubin is taken up by liver hepatocytes and converted to conjugated bilirubin.4,6 Conjugated bilirubin is water soluble and is transported from liver hepatocytes into the biliary tract system where it passes to the intestines and is excreted into the stool.

The most common type of light used is blue light (420-560 nm in wavelength). how to calculate fractionated bilirubin.
