Problems solved by technology

Although tuberculosis bacteriological examination is the "gold standard" for tuberculosis diagnosis, the smear-positive rate is low and culture takes a long time, which cannot meet the clinical needs, especially the diagnosis of bacterial negative pulmonary tuberculosis, extrapulmonary tuberculosis and childhood tuberculosis is very difficult, while immunology It is convenient, simple, fast, sensitive, and specific to check the source of specimens, and has become an important auxiliary inspection method for tuberculosis

Abstract

The invention discloses a mycobacterium tuberculosis IgG antibody enzyme-linked immunosorbent assay (ELISA) kit and preparation and application methods thereof. The mycobacterium tuberculosis IgG antibody ELISA kit comprises a TB-IgG enzyme label plate, a TB-IgG enzyme conjugate solution, a substrate solution A, a substrate solution B, a TB-IgG critical control solution, a TB-IgG positive control solution, a stop solution, a sample diluent and a concentrated detergent. The kit applies an indirect ELISA method for detecting a mycobacterium tuberculosis IgG antibody so as to reduce the interference of a false positive or false negative phenomenon in clinical diagnosis, the kit can be used for rapidly and accurately detecting mycobacterium tuberculosis, and meanwhile the kit is small in error, high in detection sensitivity and low in requirements on detection equipment.

Description

technical field [0001] The invention relates to the technical field of biological detection, in particular to an ELISA kit for Mycobacterium tuberculosis IgG antibody and a preparation and use method thereof. Background technique [0002] Mycobacterium tuberculosis (M.tuberculosis) is referred to as tuberculosis (tuberclebacilli, TB). As early as 1886, German bacteriologist Koch had proved that TB is the pathogenic bacteria of tuberculosis. The bacteria can invade various tissues and organs of the whole body, but the most common infection is the lungs. With the continuous development of anti-tuberculosis drugs and the improvement of sanitary living conditions, the morbidity and mortality of tuberculosis once dropped sharply. After the 1980s, due to factors such as the emergence of AIDS and TB drug-resistant strains, the application of immunosuppressants, drug abuse, poverty, and population mobility, the epidemic situation of tuberculosis worldwide deteriorated suddenly. A...
