[A non-invasive method of evaluation of Helicobacter pylori urease activity: its perfection and introduction to clinical practice].
The authors have developed a highly sensitive method of non-invasive diagnostics of Helicobacter pylori, the most frequent human infection. Detection of urease activity is based upon measurement of the degree of the elevation of stable 13C isotope content in exhaled air after administration of C-urea as a test reagent. The method has been scarcely applied in Russia because the test preparation, 13C urea had not been produced domestically until 2002. The method can be easily applied by any healthcare institution; however, it requires special equipment and trained personnel to perform measurement of 13C content in exhaled air samples using mass spectrometers. The article presents the first experience in clinical application of the method.
