What this trial studies
This study aims to gather clinical data necessary for the development of a non-invasive device that measures blood glucose levels through the analysis of volatile organic compounds in exhaled air. Participants, including those with type 2 diabetes and individuals at risk, will have their breath analyzed alongside traditional blood glucose measurements. The study will utilize prototypes of the Module In a Box, which were previously tested for their ability to estimate blood glucose levels. The goal is to refine the algorithm for accurate glucose level estimation based on breath analysis.
Why it matters
Potential benefit: If successful, this study could lead to a revolutionary non-invasive method for monitoring blood glucose levels in patients with type 2 diabetes.
How similar studies have gone: Previous studies have shown promising results in using breath analysis for glucose measurement, indicating potential for this innovative approach.
