    The main purpose of those investigations was optimisation of the performing time of the breath test with {sup 14}C-labelled urea which reveals Helicobacter pylori infection. It was analysed 117 species, preselected according to endoscopy and histopathology results, 56 of them have suffered from chronic gastritis and 61 from gastric ulcer disease. Using microbiology diagnosis (culture + IFP test) it was found that 86 species were H. pylori infected. This group of patients were next subject to investigations with the breath test with {sup 14}C-labelled urea. Measurements of radioactivity of breathe air have been carried out for 30 minutes. The obtained results allow us to maintain that the optimal time of duration of the test described above is 30 minutes. (author) 38 refs, 2 tabs, 1 fig
