Research output: Contribution to journalArticle


The hydrogen-breath test represents a simple and non-invasive tool, widely used mainly to diagnose carbohydrate malabsorption and bacterial overgrowth in the small intestine. Its diffusion, due to the low cost, simplicity and reproducibility, has not always been accompanied by a parallel awareness of its limits. Moreover, methodological issues have sometimes been disregarded and several methodological aspects are not yet standardized. The aim of the 'Methodology' audit was, therefore, to evaluate data supporting the different test protocols, taking into account both technical and practical aspects. These points should not be considered as minor details as the accuracy of the test is strictly related to a correct methodology.
