Summary

This study tests a small, noninvasive device that analyzes breath to detect high and low blood sugar events in children and young adults with diabetes. Participants aged 7–25 who already use a continuous glucose monitor will provide breath samples during normal, high, and low blood sugar periods. The goal is to see if the sensor can accurately estimate glucose levels without finger sticks.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Miniaturized breath sensing device
What this could lead to
If successful, this could lead to a painless, noninvasive way for people with diabetes to monitor their blood sugar levels using just their breath.
What could go wrong
This is a small, early-stage study with only 40 participants. The device's accuracy is still being tested, and it may not work as well in real-world settings or for all age groups.
