Bilirubin (paediatric), Plasma

Diagnostic Use

Bilirubin is a waste product produced by the metabolism of haem. Bilirubin undergoes conjugation with glucuronic acid in the liver before being excreted into the bile where it undergoes further metabolism and enterohepatic recycling. Most of the synthesised bilirubin is eventually excreted in the stool as the pigments stercobilin, mesobilin and urobilin.

The neonatal (paediatric) bilirubin assay is calibrated to measure the high concentrations of bilirubin that are often seen in the first few days of life.
