A groundbreaking device named isaac is emerging as a potential game-changer in glucose monitoring. This small, quarter-sized gadget developed by PreEvnt analyzes breath to detect volatile organic compounds, particularly acetone, which are linked to blood glucose levels. The breath-based approach aims to reduce the need for frequent and uncomfortable finger-prick tests.

The invention was inspired by the inventor's grandson, who has type 1 diabetes, driving years of research with institutions like Indiana University. isaac is designed for everyday use, with readings sent to a smartphone app. Clinical trials have been conducted with adolescents and adults since 2025, and the company is pursuing FDA approval via a de novo pathway.

While isaac is not intended to replace medical-grade meters, it promises to supplement current monitoring methods by offering early, non-invasive alerts. If approved, this technology could significantly ease the daily burden for individuals managing diabetes, making life easier and safer. The companion app is expected to launch on iOS and Android closer to the device's availability.
