Specimen Minimum Volume: 1 mL

Rejected Due To

  • Unacceptable container type
  • Sample received past listed stability

Interpretation

Peritoneal: Peritoneal bilirubin concentrations greater than that of serum/plasma may suggest bile within the abdomen.

 

Drainage: Drain fluid bilirubin concentration-to-serum/plasma bilirubin concentration ratios exceeding 5 indicates bile leakage.

Cautions

Total bilirubin results may be falsely decreased in the presence of gross hemolysis. In some cases of monoclonal gammopathies (especially Waldenstrom's macroglobulinemia with very high concentrations of IgM), total bilirubin results may be unreliable. Total bilirubin results may be falsely low in the presence of high concentrations of N-acetyl-p-benzoquinone imine (metabolite of Acetaminophen).

Method Description

Photometric with 3,5-dichlorophenyldiazonium tetrafluoroborate (DPD), and caffeine and a surfactant as accelerators.
