Problems solved by technology

However, due to the insufficient preparation process of quality control products, the stability of quality control samples used for reagent assessment, indoor quality control and external quality assessment in China is not high. The results of quality control and quality evaluation have large deviations. On the one hand, it affects the correct judgment of laboratory test results, and even directly endangers the accuracy of test results. Risk of administrative confusion and technical difficulties

Abstract

The invention discloses a special diluent for an alkaline phosphatase antigen-antibody. The special diluent is prepared from the following components in percentage by mass: 92 to 95 percent of phosphate buffer, 1 to 3 percent of polymer hydrophilic compound, 0.2 to 0.5 percent of sodium ethylene diamine tetracetate, 0.01 to 0.02 percent of preservative, 1 to 3 percent of modified amino acid, 0.02to 0.04 percent of an anticoagulant, 0.05 to 0.12 percent of fibroin and 2.68 to 5.72 percent of nano silver powder. Compared with the prior art, the special diluent for the alkaline phosphatase antigen-antibody, disclosed by the invention, has the advantages of simple components, good hydrophilicity and high capability of stabilizing the activity of the antigen-antibody labeling alkaline phosphatase; in addition, the required quantity is low, so that the production cost is reduced.

Description

Technical field [0001] The invention relates to the field of medicine, in particular to a special diluent for alkaline phosphatase antigen and antibody. Background technique [0002] The quality of laboratory testing is related to the clear diagnosis and condition monitoring of patients. In the field of blood infectious disease screening, the correctness of the test results is also closely related to the safety of blood. The quality assessment of the reagents used, the implementation of indoor quality control for infectious disease detection, and participation in an appropriate external quality evaluation system are a series of methods to ensure the quality of testing. However, due to the insufficiency of the quality control product preparation process, the stability of the quality control samples currently used for reagent assessment, indoor quality control, and external quality assessment in China is not high. An important reason is that the degradation of quality control sampl...
