This test uses Roche CA 19-9 electrochemiluminescent immunoassay. Results obtained with different test methods or kits cannot be used interchangeably. CA 19-9 is useful in monitoring pancreatic, hepatobiliary, gastric, hepatocellular, and colorectal cancer. CA 19-9 value regardless of level, should not be interpreted as absolute evidence of the presence or absence of malignant disease.
No compliance statements are in use for this test.
