Thanks to the exceptional accuracy1 of Dexcom ONE CGM, you can make treatment decisions, like insulin dosing, without finger pricks* or scanning. Dexcom ONE doesn't require any calibration to deliver accurate readings unlike other blood glucose monitoring systems.
* If your glucose alerts and readings from the Dexcom ONE do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions.
Your Dexcom ONE system can alert you whenever your glucose level falls outside of your preset High and Low glucose levels, so that you can take action. You can customise the alerts and even delay your first high alert.
The Dexcom ONE glucose sensor can be worn up to 10 days and has a slim profile, making it nearly invisible under clothing. Thanks to the sensor auto-applicator, it only takes the push of a button to insert the sensor's wire in an instant beneath the skin. In a study, 84% of Dexcom users reported painless sensor insertion2.
Get started on your journey to zero finger pricks* or scanning with our simple self-guided training programme.
