High baseline breath hydrogen
Web20 de ago. de 2024 · A positive test was defined as a ≥20 ppm rise of hydrogen or methane from baseline. A high methane producer had an initial reading of ≥5 ppm. Breath hydrogen and methane production were measured as area under the curve. Chi-squared tests were used to compare proportions of those meeting the cut-off criteria. Results Web13 de jun. de 2024 · With the aim to decrease the number of high baseline H 2 and/or CH 4 levels detected during the performance of breath tests, we evaluated the effect of the time of procedure and a previous light walk.

WebBackground: Levels of breath methane, together with breath hydrogen, are determined by means of repeated collections of both, following ingestion of a carbohydrate substrate, at 15-20 minutes intervals, until 10 samples have been obtained. The frequent sampling is required to capture a rise of hydrogen emissions, which typically occur later in the test: …
