Quantitative Electrochemiluminescent Immunoassay
Within 24 hours
Biliary/Hepatic, CSF, Pancreatic, Peritoneal/Ascites, or Pleural fluid.
Centrifuge to remove cellular material. Transfer 1 mL body fluid to an ARUP Standard Transport Tube. (Min: 0.5 mL)
Specimen types other than those listed. Specimens too viscous to be aspirated by instrument.
Specimen source must be provided.
Ambient: 8 hours; Refrigerated: 5 days; Frozen: 3 months
The Roche CA 19-9 electrochemiluminescent immunoassay is used. Results obtained with different test methods or kits cannot be used interchangeably. The CA 19-9 value, regardless of level, should not be interpreted as absolute evidence of the presence or absence of malignant disease.
