In this article the comparative analysis of various methods of Helicobacter pylori verification is shown. Also algorithm of optimization of helicobacteriosis diagnostic, developed on the basis of a comparative estimation of results of various diagnostic techniques is presented. According to this algorithm, for increase of accuracy of helicobacteriosis diagnostic it is recommended to use at least two, and it is better three diagnostic methods: the combination of fast urease test or Helic-test with a histologic method (biopsy material from a stomach corpus) or polymerase chain reaction (ureC gene detection) is preferable. For an efficiency estimation of eradication therapy we recommend "Helic-test" as an effective noninvasive method that is especially important for children.
