Monitoring Exhaled Breath to Noninvasively Detect Glycemic Events

Summary

The purpose of this study is to determine whether an array of biosensors can noninvasively identify hyperglycemic or hypoglycemic events in persons diagnosed with diabetes through noninvasive detection of volatile organic compounds in exhaled breath.
