Dexcom ONE+ Sensor

About Dexcom ONE+ Sensor

The Dexcom ONE+ Sensor is a real-time continuous glucose monitoring (rtCGM) device designed for people aged 2 years and over, including during pregnancy. It measures glucose levels in the interstitial fluid using a small sensor worn on the skin and automatically sends readings every 5 minutes to a compatible smartphone or an optional receiver.

Dexcom ONE+ allows users to view current glucose levels, trend arrows, and up to 24-hour glucose history, helping to monitor patterns and make confident diabetes management decisions. Each sensor provides up to 10 days of wear and is applied using an easy, all-in-one disposable applicator.
