Still the same high-performing CGM

It starts with an accurate sensor. Dexcom CGM is not only appealing, but delivers results consistently and accurately.1

How does Continuous Glucose Monitoring work?

The Dexcom G4 PLATINUM CGM System unveils what no meter can. While meters give a number for a single point in time, CGM provides dynamic glucose information by showing where glucose is, where it’s going, and how fast it’s getting there.


Dexcom’s G4 PLATINUM CGM System consists of 3 parts1:


1. Small Sensor that measures glucose levels just underneath the skin.

2. Transmitter that is fastened on top of the sensor and sends data wirelessly to the receiver.

3. Receiver that displays your glucose trends in vivid colors so you can easily see when it’s high, low or within range.
