Helicobacter pylori Antigen Detection Kit is a rapid chromatographic immunoassay for the qualitative detection of Helicobacter pylori Antigen in the human feces. It is used for professional in vitro diagnostic use only.
INTRODUCTION
Helicobacter pylori (Helicobacter pylori, H. pylori) is a gram-negative spiral bacteria in gastric epithelial cells settle reproduction. After H. pylori infection can cause gastritis, peptic ulcers, mucosal-related lymphoma, and even lead to gastric cancer. Detection of H. pylori using the traditional method is the direct microscopic examination of pathological specimens, microbial culture and urease test. Modern methods are immunological techniques for detecting antigen or antibody, and detecting the nucleic acid sequences by molecular biology techniques. Depending on the material used for the detection, laboratory diagnosis of H. pylori is divided into two categories: (1) invasive test: it is to get the gastric mucosa through the endoscope as the test material, microbiological culture, histopathology detection, rapid urease test and genetic diagnosis; (2) non-invasive tests: no need to obtain the gastric mucosa, using gastric juice, serum, saliva, feces samples, the method of H. pylori stool antigen test, serum H. pylori tuberculosis antibody test, urea breath test and stool and determination of H. pylori genes other specimens. The author of Helicobacter pylori infection in laboratory diagnostic methods are reviewed in order to fully understand the various detection methods and applied Clinical.
PRINCIPLE
The Helicobacter pylori Antigen Test (Human feces) is a lateral flow chromatographic immunoassay based on the principle of the double antibody-sandwich technique. The membrane is pre-coated with anti-Helicobacter pylori antibodies on the test line region of the test. During testing, the specimen (Human feces) reacts with the particle coated with anti-Helicobacter pylori antibody. The mixture migrates upward on the membrane chromatographically by capillary action to react with anti-Helicobacter pylori antibodies on the membrane and generate a coloured line. The presence of this colored line in the test region indicates a positive result, while its absence indicates a negative result. To serve as a procedural control, a colored line will always appear in the control line region indicating that the proper volume of specimen has been added and membrane wicking has occurred.
