Summary
This sensor lasts for 10 days and only needs finger sticks as a backup. Dexcom G6 has 3 parts - sensor, transmitter, and receiver. Data can be viewed on a compatible mobile device or a separate receiver. Optional low and high blood sugar notifications are available for this system.
FDA approved for insertion on the abdomen (indicated for patients age 2 years and older) or the upper buttocks (ages 2-17 years).
MARD of 9%
Loop is a DIY (do-it-yourself) system. It takes some work to set up but allows people to think about diabetes less by automating basal insulin delivery based on predicted glucose levels. This system can be used with the Dexcom G6 and the Omnipod or Medtronic pumps. Information about DIY Loop can be found on the Loop or Riley Link websites.
Components
Dexcom G6 : Sensor
Sensor uses a thin, flexible filament inserted just under the skin to measure glucose levels every 5 minutes. Push-button applicator allows sensor to be placed on the body in one step.
Dexcom G6 : Transmitter
Sends readings from sensor to device, clips into sensor. Can be used for 90 days.
Dexcom G6 : Receiver
Receives data automatically from the transmitter. Can be substituted by compatible smartphone and smartwatch. Available for both iOS and Android devices.
Loop : Pump
The system is compatible with Omnipod (left) or Medtronic (right) pumps. Both options can be applied anywhere on the body that is comfortable.
Loop : Sensor
Automatic applicator inserts sensor just under the surface of the skin and can be applied to many places on the body.
DIY Loop : Transmitter
RileyLink allows the pump and sensor to communicate. It is only required if a Medtronic pump is used.
Loop : Controller
Smartphone or smartwatch receives CGM readings and automatically adjusts insulin delivery via an Omnipod or Medtronic pump.
Device Details
Overview
Small sensor can be worn in multiple areas.
This is a DIY (do-it-yourself) system that needs significant setup. It has the most flexibility in settings and device options. It also depends on a third device called a "Riley Link" to communicate between sensor, phone, and pump.
Affordability and Access
$$$$
Widely covered. Provided by DME and/or Pharmacy. Price range; $0-$500/month.
$$$$
Supplies can be covered for Omnipod or Medtronic pumps and Dexcom. Price range; $0-$8,574 to start and 0-$300/month. iPhone, app, and Riley link are not covered and must be set up independently. Riley link price range; $135-$165.
Data Monitoring Options
Yes
Automatically and continuously sends data to the user’s Dexcom Clarity web-based cloud which is accessible by clinicians. Data upload is possible with Glooko and Tidepool data-management systems.
Yes
Compatible with Tidepool - a web-based diabetes data management system.
Data View Options
Yes
Users must download the Dexcom G6 and Dexcom Clarity apps to view and share data. Both apps provide multiple data views, sharing options, and access through the clinician portal using a code from the user's device. Caregivers can use the Dexcom Follow app to view data. Glooko and Tidepool can also be used to view data.
Yes
Data can be viewed on an iPhone.

Patient Considerations
Active Lifestyle
Water-resistant when submerged in 2.4 meters of water and must be within 20 (unobstructed) feet of the receiver or mobile device.
Automatic responses. Can set custom blood sugar targets and insulin and carb sensitivities based on type of activity. App automatically responds to blood sugar changes during activity. *Medtronic option is not waterproof. Omnipod option is fully waterproof.
Avoiding Highs and Lows
Custom alerts can be set for highs, lows, and rapidly rising or falling glucose levels. Trend arrows show the direction glucose is heading, with the rate of change.
Automatically adjusts insulin delivery. Increases or decreases insulin delivery to meet glucose targets. Insulin delivery settings can be aggressive or conservative.
Comfort
Low profile and low maintenance sensor application.
Low-profile but extra device. Low profile/low maintenance sensor. The RileyLink is an extra device that must be carried.
Easy Insulin Dosing
Real-time data and alerts make dose adjustment easier.
All settings are completely customizable. Can bolus from phone or smartwatch. Can operate “open-loop” where the user must enact insulin delivery based on recommendations or “closed-loop” where modifications to insulin delivery are automatically delivered.
Easy to Use
Flexible pump integration. Can be paired with multiple different types of pumps which gives flexibility for how to use the data.
Difficult set-up but easy to use. Software makes most dosing decisions. Requires many parts. Can be difficult to set up.
Fewer Fingersticks
Factory-calibrated sensor. Finger sticks needed for backup only.
Factory-calibrated sensor. Fingersticks needed for backup only.
Privacy
Hypoglycemia safety alarm. Discreet but built-in hypoglycemia safety alarm alerts users when glucose is below 55 mg/dl and is always on.
Discreet. Ability to give insulin via watch or phone. Ability to check sugar on phone or watch. Alerts available. *Medtronic pump has tubing. Omnipod is most hideable pump option (no tubes or separate controller needed).
