CA19-9 is a tetrasaccharide attached to O-glycans on the cell surface essential for the cell-to-cell recognition process. CA19-9 is produced in the pancreases, biliary tract, gastric, colonic, and uterine mucosa, and the salivary glands. It has been reported to show increase in the stomach, colorectal, lung, thyroid, as well as biliary and pancreatic cancers, thus acting as a tumor marker primarily in the management of pancreatic cancer. It is used as a positive control in the ELISA test kit for the detection of cancers.
