Description
Overview
Stelo is Dexcom’s over-the-counter integrated continuous glucose monitor (iCGM) for adults 18 and older who are not on insulin. An applicator inserts a thin, flexible sensor wire under the skin, and the attached transmitter sends glucose values by Bluetooth to the Stelo app, which shows the current value and the direction it is heading.
Each box holds two biosensors, and each one is worn for up to 15 days before it is replaced.
