Poster Audio: Development and Validation of a Portable Device for At-Home Hydrogen and Methane Breath Testing

Hydrogen and methane breath tests (HMBTs) can be used in the clinic to diagnose small intestinal bacterial overgrowth (SIBO) and carbohydrate malabsorption (CM) due to the connection between the levels of these gases in the breath and the activity of the gut microbiome. Longitudinal measurement of hydrogen and methane, as opposed to a single sample, allows for the monitoring of treatment response and early detection of disease recurrence. We have developed the OMED Health Breath Analyzer for this purpose. In our recent study, we undertook several validation tests to measure the accuracy of the OMED device. These tests included simulating human breath to allow us to measure hydrogen and methane across a range of temperatures and humidities and benchmarking the device to an in-clinic hydrogen and methane analyzer using the breath of human volunteers.

This study found that the OMED device is highly accurate with comparable performance to an in-clinic HMBT. The added portability for convenience and the possibility of taking regular at-home measurements can provide significant benefits for users by providing longitudinal data that is immediately available to their healthcare provider.

We recently presented this work at the American College of Gastroenterology (ACG) conference, and you can view our presentation below. If you are interested in finding out more, or meeting us at a conference, please get in touch.

We also presented this study at the 2024 Breath Biopsy Conference, which you can view here.
