Using your Dexcom G6 CGM System
Calibration and Accuracy Issues
Is my Dexcom sensor accurate?
The test your doctor does is considered a more accurate glucose number than any products you use at home. Both BGMs and Dexcom G6 are compared to that doctor’s test to measure accuracy in clinical studies.
Why does my Dexcom G6 say I'm low at night when my BG meter shows otherwise?
One explanation may be that something is pressing on your sensor which can affect your Dexcom G6 readings. Once the pressure is relieved, your Dexcom G6 readings should be closer to your blood glucose meter.
Does the G6 accept calibrations?
The option to enter calibrations was included to allow a user to manually calibrate the system in case the start-up calibration code is lost.
