The Roche Modular E170 CA 19-9 electrochemiluminescent immunoassay is used. Results obtained with different assay methods or kits cannot be used interchangeably. CA 19-9 is useful in monitoring pancreatic, hepatobiliary, gastric, hepatocellular, and colorectal cancer. The CA 19-9 assay value, regardless of level, should not be interpreted as absolute evidence of the presence or absence of malignant disease. This test is FDA cleared but is not labeled for use with body fluids.
