Аннотация
We have evaluated a 13C-urea breath test for the diagnosis of Helicobacter pylori infection. The 13C-test was analyzed with isotope-selective nondispersive infrared spectrometry and compared with a 14C-urea breath test and the urease test in gastric mucosal biopsies. 46 patients were analyzed with breath tests; 23 patients were negative and 22 patients were positive with both methods. One patient was positive with the 14C-method and negative with the 13C-urea breath test. 61 patients were analyzed with the 13C-urea breath test and the urease test. 30 patients were negative and 30 patients were positive with both methods, whereas one patient with a negative urease test had a positive breath test. 13C-urea breath test analyzed with isotope-selective non-dispersive infrared spectrometry is a fast, simple, non-radioactive, non-invasive, convenient and reliable method for the diagnosis of Helicobacter pylori infection.
