Abstract

The invention discloses a helicobacter pylori antibody detection kit, comprising the following constituents: a magnetic microsphere solution directly coating or indirectly connecting helicobacter pylori antigen; and a marking tracer solution directly coating or indirectly connecting anti-human IgG antibody; and / or a marking tracer solution directly coating or indirectly connecting anti-human IgM antibody; and / or a marking tracer solution directly coating or indirectly connecting anti-human IgA antibody; and / or a marking tracer solution directly coating or indirectly connecting staphylococcus aureus A protein. The invention further discloses a corresponding helicobacter pylori antibody detection method and application thereof. The kit, the method and the application provided by the invention can detect various antibodies, including helicobacter pylori IgG antibody, helicobacter pylori IgM, helicobacter pylori IgA and total helicobacter pylori antibody, are applicable to complex conditions of helicobacter pylori infected person better, moreover, can accurately detect the helicobacter pylori antibody without pre-dilution to samples.

Description

technical field [0001] The invention relates to chemiluminescent immunodetection technology, in particular to a helicobacter pylori antibody chemiluminescent immunodetection kit, detection method and application. Background technique [0002] In 1982, Australian scholar Marshall observed a bacterium in the gastric mucosa that was associated with the onset of chronic gastric disease. In 1989, Goodwin et al. named it Helicobacter pylori (HP), which was recognized by the academic community. In 1994, the World Health Organization / International Agency for Research on Cancer (WHO / IARC) designated Helicobacter pylori as a human I carcinogen. Helicobacter pylori is a unipolar, multi-flagellate, blunt-rounded, spirally curved bacterium with a length of 2.5-4.0 μm and a width of 0.5-1.0 μm. It often presents a typical spiral or arc on the surface of gastric mucosal epithelial cells; When growing on solid media, in addition to the typical morphology, sometimes rod or spherical shapes...
