Immuno-enzymatic colorimetric method for the quantitative determination of CA19-9 concentration in human serum or plasma. CA19-9 ELISA is intended for laboratory use only.
CA19-9 represents the most important tumour marker of the mucin type glycoproteins group, that are associated to gastrointestinal cancer pathology. The immunohistologic distribution of CA19-9 in tissues is consistent with the quantitative determination of higher CA19-9 concentrations in cancer than in normal or inflamed tissues. Recent reports indicate that the serum CA19-9 level is frequently elevated in the serum of subjects with various gastrointestinal malignancies, such as pancreatic, colorectal, gastric and hepatic carcinomas. Together with CEA, elevated CA19-9 is suggestive of gall bladder neoplasm in the setting of inflammatory gall bladder disease. This tumour associated antigen may also be elevated in some non-malignant conditions.
It has been shown that a persistent elevation in serum CA19-9 value following treatment may be indicative of occult metastatic and/or residual disease. Research studies demonstrate that serum CA19-9 values may have utility in monitoring subjects with the above mentioned diagnosed malignancies. A persistently rising serum CA19-9 value may be associated with progressive malignant disease and poor therapeutic response. A declining CA19-9 value may be indicative of a favourable prognosis and good response to treatment.
