Our initial goal was to show that our device was as accurate as the gold-standard clinical device. This study was presented at the British Society of Gastroenterology in 2019. The abstract is also published in the journal Gut. Another successful validation was conducted by University of Auckland and published in the journal Nutrients, also in 2019. Our device was able to identify 100% of patients with lactose intolerance.
Our next goal was to compare the accuracy of our device to the mail-in breath test kits. Since August 2020, we’ve been involved in a clinical trial at Johns Hopkins Medical Center. Data from this trial has been presented at the 2021 Digestive Disease Week and the 2021 American College of Gastroenterology conference, showcasing that our device was as accurate as the mail-in breath kits.
Having successfully validated our device against established clinical devices and tests, our final goal was to measure the accuracy of our device using gas chromatography mass spectrometry (GC-MS). This was successfully conducted by an expert gas sensing lab (ISO accredited) and demonstrated that the device was accurate to 1 part per million of hydrogen.
