Abstract
Description
technical field
[0001] The invention belongs to the technical field of in vitro diagnostic testing, in particular to a method for testing a cancer blank antigen calibrator. Background technique
[0002] Carcinoembryonic antigen (CEA) is a carbohydrate antigen with a specific determinant of human embryonic antigen, which is an important tumor-associated antigen. synthesized by hepatocytes. In 1965, Gold and Freedman first discovered it from fetal and colon cancer tissues, so they called it carcinoembryonic antigen. Its coding gene is located on chromosome 19 and is a polysaccharide-protein complex with a molecular weight of 22KD, 45% of which is protein.
[0003] CEA is a non-organ-specific tumor-associated antigen, which mainly exists in rectal and colon cancer tissues and fetal intestinal mucosa. Most of the tumors that secrete CEA are located in hollow organs, such as the gastrointestinal tract, respiratory tract, and urinary tract. Under normal circumstances, CEA is me...
