Bilirubin (Conjugated)

Alias: N/A

Discipline: Clinical Chemistry

Test information: In serum or plasma the terms “indirect” and “direct” bilirubin are often used to refer to unconjugated and conjugated bilirubin respectively; the difference being that the indirect fraction requires a solubiliser (originally methanol) to effect a reaction whereas the direct fraction reacts without a facilitating agent.
