Carcino-embryonic antigen calibrator test method

Abstract

A carcino-embryonic antigen calibrator test method is disclosed. The carcino-embryonic antigen calibrator test method includes the following preparation steps: 1) dividing to-be-tested calibrators into two groups, respectively testing the luminescence value of the to-be-tested calibrators, a working reference product and a quality control product; 2) using the working reference product as a curvefor fitting of the to-be-tested calibrators and the quality control product, and calculating the values of the to-be-tested calibrators and the quality control product; 3) using the to-be-tested calibrators as a curve for fitting of the quality control product, and calculating the values of the to-be-tested calibrators; 4) assigning, to be more specific, assigning the sub-packaged calibrators; and5) verifying, to be more specific, respectively determining inter-bottle homogeneity and the in-bottle homogeneity. The carcino-embryonic antigen calibrator test method can accurately detect the calibrator of a carcino-embryonic antigen (CEA), is accurate in measurement value, can effectively monitor a test value of a sample in a clinical test, and has the advantages of low cost, high efficiency,accurate assignment, mass production convenience compared with a test method used in the prior art.

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...

AI Technical Summary

Problems solved by technology

[0007] The combined detection of carcinoembryonic antigen and other tumor markers is helpful for the diagnosis of liver cancer, colon cancer, rectal cancer, gastric cancer and lung cancer, as well as the dynamic monitoring of radiochemical efficacy, to assist in judging the disease process or treatment effect, and cannot be used as an early diagnosis or treatment for malignant tumors. Basis for diagnosis

The detection of carcinoembryonic antigen is currently carried out by quantitative methods in the market, so the calibrator is an indispensable reagent component. At present, there is no standardized and unified inspection method in the calibrator value market
