Pre-publication

Improving the Diagnosis of Small Intestinal Bacterial Overgrowth Using an At-Home Handheld App Connected Breath Analysis Device (AIRE)
Barahona G. et al. medRxiv 2022.

Clinical Trials

Ongoing

Clinical Utility of Handheld Hydrogen Breathalyzer in Identification of Food Sensitivities (AIRE Study)

Completed

Gut health in Australia and Singapore for Science and Innovation (GASSI) study. A multi-centre study comparing dietary sensitivities in Asian and Australian populations. FoodMarble AIRE was used to test for the malabsorption of four common carbohydrates and to track participant symptoms. Publication in preparation, expected in late 2022.
FoodMarble Internal Prebiotic Study. A double blind cross-over study examining individual breath hydrogen and microbiome response to selected prebiotics. Breath hydrogen was significantly correlated with Bifidobacterium indicating the potential of using FoodMarble AIRE to track prebiotic induced microbiome changes.
