Description

technical field [0001] The invention relates to the field of in vitro diagnosis of medical immunity, in particular to an apolipoprotein A1 detection 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...
