OBJECTIVES Currently, the (13)C-urea breath test is the reference method for non-invasive diagnosis of Helicobacter pylori infection and therapy control. Therefore, new technologies have been developed to measure the ratio of (13)CO(2)/(12)CO(2) in breath. The laser-assisted ratio analyser (LARA) device is based on optogalvanic effects of the stimulated CO(2) molecules. DESIGN In this study, the LARA system is prospectively compared to conventional isotope ratio mass spectrometry (IRMS… CONTINUE READING
