Understand your blood glucose status and fluctuations. Transform – Begin with iFree CGM.
What is CGM?
Continuous Glucose Monitoring System (CGM) involves wearing a sensor on the user’s body to measure glucose levels in the interstitial fluid. Through chemical reactions, the sensor generates an electric current that is converted into blood glucose values. The measured data is then transmitted to a reading device for continuous monitoring of the user’s glucose fluctuations.
iFree CGM, used in conjunction with a mobile device and dedicated app, offers continuous monitoring for up to 14 days, 24 hours a day 1. It provides clear and accurate data to assist users in better managing their blood glucose levels.

Abbreviations：
CGM = Continuous Glucose Monitoring System；
AGP = Ambulatory Glucose Profile；
TIR = Time In Range，Time in Range (TIR) is a critical indicator for assessing blood glucose control, representing the percentage of time that blood glucose values remain within the normal range。
Precautions：
1. Calibrate every 24 hours.。
2. Confirm with fingertip test if glucose values and alerts don’t match symptoms.
3. Data may be temporarily unavailable if receiver or phone is out of transmitter’s range or obstructed.
4. Waterproof up to 3.05 meters for 30 hours; use waterproof tape if adhesive lifts.
5. Exclude aircraft and pressurized cabins.
