About Continuous Glucose Monitors


This article provides an overview of what a CGM is, the types of CGMs that Levels supports, and how they are prescribed.

What is a continuous glucose monitor?

A continuous glucose monitor (CGM) measures glucose with a thread-like filament that sits under the skin. With a CGM, your blood glucose is measured based on interstitial glucose - which is the fluid between skin cells. 

Continuous glucose monitoring (CGM) devices have traditionally been used to replace finger-prick blood glucose testing for detecting trends and tracking patterns in glucose levels in persons with diabetes. The systems are intended for single patient use and require a prescription.

What type of CGMs does Levels support?

Levels supports the FreeStyle Libre CGM and the Dexcom G6 CGM

How are these devices prescribed?

The FreeStyle Libre & Dexcom G6 CGM are prescribed by our partner physicians to qualifying Levels members for general health information and wellness purposes, to observe trends and relationships between diet and lifestyle choices and glucose levels. CGMs acquired through a Levels partner-physician are not intended for, and should not be used for the observation or treatment of any medical condition, disease, or diagnosis, including diabetes.
