Smart & Accurate6
Dexcom ONE+ is an accurate CGM system6. It allows for confident treatment decisions in real-time (such as dosing insulin) and no fingerpricks*. Sending 24/7 real-time glucose numbers to your smartphone† or receiver‡, it automatically alerts you when your glucose levels fall out of your pre-set range.
Customisable high and low glucose alerts:
Dexcom ONE+ offers the essential Dexcom alerts to meet your needs. With customisable high and low alerts, you know when glucose levels fall outside of an adjustable and preset high and low glucose range.

The Dexcom ONE+ continuous glucose monitoring system is a glucose monitoring system indicated for continuously measuring glucose in the interstitial fluid in persons ages 2 years and older, including pregnant women. Dexcom ONE+ is designed to replace fingerprick blood glucose (BG) testing for treatment decisions. Interpretation of Dexcom ONE+ results should be based on glucose, trends and several sequential sensor readings over time. Dexcom ONE+ also aids in the detection of episodes of hyperglycaemia and hypoglycaemia, facilitating both acute and long-term therapy adjustments. Dexcom ONE+ is intended for use by patients at home and in healthcare facilities.
