Dexcom G7

As of August 2026 we track 4 continuous glucose monitors available here, and the cheapest one you can buy without a prescription is the Sibionics GS1 at about 125,98 € a month.

Was bedeutet der Genauigkeitswert?

MARD ist die durchschnittliche Abweichung zwischen Sensorwert und Laborblutwert in Prozent. 10% MARD heißt: die Werte weichen im Mittel um rund 10% ab. Niedriger ist besser. Aktuelle Sensoren liegen meist unter 10%; vor zwanzig Jahren waren es über 20%. Kein Sensor ist exakt.

Das überzeugt

  • Thirty-minute warm-up, the shortest of the medical sensors here
  • Strong alarm and follower support, including remote monitoring for a parent or partner
  • Works with several automated insulin delivery systems

Darauf sollten Sie achten

  • Ten days of wear means more sensor changes than the fifteen-day Abbott sensors, and a higher yearly cost
  • An independent head-to-head study measured 13.6% MARD, well above the 8.2% pivotal figure
  • UK prices are quoted excluding VAT — you only avoid the 20% if you can claim diabetes VAT relief

Unser Fazit

The sensor to pick if you want alarms, remote following, or pump integration. The gap between its pivotal accuracy figure and the independent one is the widest of any sensor we list, and worth knowing about.

  • CGM accuracy: what MARD means, and what it hides

    MARD is the average gap between a sensor and a laboratory blood test. It is the standard accuracy figure, it is genuinely useful, and it is routinely compared between studies that cannot be compared.

Häufige Fragen

How accurate is the Dexcom G7?
Dexcom’s pivotal study reported 8.2% MARD for arm placement and 9.1% for the abdomen. An independent head-to-head study of 55 adults reported 13.6%.
How long does a Dexcom G7 sensor last?
10 days, with a grace period after that before the sensor stops reading.
