A closer look at the Dexcom ONE Components

Dexcom ONE measures glucose levels up to every five minutes using a sensor inserted just underneath the skin, and wirelessly transmits glucose readings to a receiver or compatible smart device.

With just a quick glance at their compatible Apple or Android smart device, people with diabetes can see where their glucose levels are heading and how fast, so they can take action.*

*If your glucose alerts and readings from Dexcom ONE do not match symptoms or expectations, use a blood glucose meter to make diabetes treatment decisions. 

Optional receiver

Dexcom ONE shares data with compatible smartphones but an optional receiver is available for people with diabetes who may not have access to such devices.
