Continuous glucose monitoring devices
| Type of CGM . | Description . |
|---|---|
| rtCGM | CGM systems that measure and store glucose levels continuously and without prompting |
| isCGM with and without alarms | CGM systems that measure glucose levels continuously but require scanning for storage of glucose values |
| Professional CGM | CGM devices that are placed on the patient in the provider’s office (or with remote instruction) and worn for a discrete period of time (generally 7–14 days). Data may be blinded or visible to the person wearing the device. The data are used to assess glycemic patterns and trends. These devices are not fully owned by the patient—they are clinic-based devices, as opposed to the patient-owned rtCGM/isCGM devices. |
