Abstract

The invention provides an immunonephelometry detection kit. The immunonephelometry detection kit comprises a reagent R1 and a reagent R2, wherein the reagent R1 contains 1-50 g / L of octylphenoxy polyethoxyethanol, the reagent R2 contains 1-50 g / L of octylphenoxy polyethoxyethanol, 0.01-15 g / L of magnesium salt, 0.01-20 g / L of calcium acetate and an antibody. The detection kit has the advantages of good performance, good repeatability, and accurate reagent detection result, and can satisfy the usage requirement.

Description

technical field [0001] The invention relates to the field of medical immune in vitro diagnosis, in particular to an immune turbidimetric kit and a detection method. Background technique [0002] Turbidimetry has been widely used in clinical testing. Now the most common application is immunoturbidimetry. [0003] Most of the early immunoassay techniques analyzed the presence and content of specific proteins in the sample to be tested by observing the formation of precipitates, the occurrence of agglutination and hemolysis, and measuring the light scattering caused by aggregates, such as immunodiffusion, Immunoelectrophoresis, direct and brief hemagglutination, passive hemagglutination, complement fixation test, etc. These detection methods are low in cost, easy to judge the results, easy to master technically, and can be widely used to detect various types of clinical samples. However, the above method tends to be eliminated due to its cumbersome operation, time-consuming a...
