FAQ: What is a Continuous Glucose Monitor (CGM)?


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.
