Guardian™ Connect CGM System is a continuous glucose monitoring system with 60 minutes predictive alerts. For people on insulin injections.



With the tools to outsmart the highs and lows of diabetes, the Guardian™ Connect continuous glucose monitoring system allows you to focus on your life — not on your levels. Using smart technology to predict where your glucose levels are headed, the system will alert you from 10 to 60 minutes before a high or low.

Connect up to 5 (five) care partners to view your sensor readings and alerts.  With the Guardian™ Connect System, care partners can view readings and alerts from any internet enabled device.

We’ve designed Guardian™ Connect CGM with value in mind. You can view your sensor readings and alerts on a compatible mobile device. You don't need to buy a separate receiver.

The Guardian Connect CGM is compatible with your iOS device. You can wear it with your pump, however please note that this is a stand-alone CGM and does not link to your insulin pump.

2. Event Markers: Track your exercise, meals, insulin doses, and other important events to see how your sensor glucose levels are impacted.

3. Your Glucose History: See your glucose readings and events for the past few hours, or the past day.

4. Log Events: Use easy navigation to quickly enter exercise, insulin notes, meals, and BGs to see how they may impact your glucose.

1. Guardian™ Connect App

Displays sensor glucose data, trends and alerts in a simple and easy to use design. The Guardian™ Connect app is part of the CGM system and is not compatible with an insulin pump.

2. Guardian™ Sensor (3) and Guardian Connect Transmitter™

The system includes a small sensor that can be worn up to seven days and a slim, discreet Bluetooth® transmitter that can only be worn with the sensor.  The sensor may be inserted in the abdomen and buttock for ages 3 to 13 and in the arm and abdomen for ages 14 and above.. And you need only one rechargeable transmitter for a year or more of use2 — unlike with some other systems whose transmitters are replaced four times as often.3

  • Do not use the Guardian Connect System for pediatric patients until you have thoroughly reviewed (with your Healthcare Professional), the system alert performance in the Guardian Connect Application User Guide and the sensor accuracy performance in the Guardian Sensor (3) Performance document. Discuss with your Healthcare Professional how to best set up your Guardian Connect System alerts to reduce the risk of missing low blood glucose or high blood glucose events.
  • In the pediatric clinical study (3-18 years of age), larger differences were observed between the Guardian Connect System and actual blood glucose values compared to those differences observed in the adolescent/adult clinical study (14-75 years of age), particularly at low glucose levels.
  • In the pediatric clinical study, a significant percentage of low glucose events were not detected by the Guardian Connect System. Do not rely solely on the Guardian Connect System alerts to detect low glucose.
  • In the pediatric clinical study, the Guardian Connect System triggered a high percentage of false low glucose and false high glucose alerts. The Guardian Connect System is not intended to make therapy adjustments: always check your capillary blood glucose before making therapy adjustments.
  • In the pediatric clinical study, enabling the ‘Alert Before Low’ and ‘Alert Before High’ predicted alerts significantly reduced the percentage of missed low blood glucose and missed high blood glucose events, but also significantly increased the percentage of false low glucose and false high glucose alerts. Do not ignore alerts from your Guardian Connect System. Always follow your treatment instructions from your Healthcare Professional when responding to an alert from your Guardian Connect System.

Smart CGM predicts future high and low sensor glucose events up to 60 minutes in advance and provides access to additional algorithms and insights that can inform users of clinically relevant glucose patterns.
