My 12 year old daughter was recently diagnosed with T1D. I have went from impressed with the Guardian 3 to now wondering what the point of using the Guardian 3 is. Looking for advice from someone that has had a Dexcom G6 and Guardian 3. Should we fight with insurance to get the Dexcom G6? I assume this will be a pain since we just got the Guardian 3 and I am not sure how their returns work. We are on the guardian 3 because her Dr was pushing Medtronic hard. If we change sensors we need to do this before she gets a pump in a few months. I appreciate any opinions and recommendations.
Here is what we have experienced so far. First sensor was placed on abdomen. Accuracy after the first day seemed fairly good and we were impressed. I seen the MARD was better for on the back of arm so we tried that with the next sensor. Accuracy ended up being good but not quite as good as the first sensor. Third sensor is where things started going down hill. On the third sensor it was placed on the abdomen. This was not the same spot as first sensor and she has never taken insulin in the abdomen. This sensor was way off with each calibration. Less than a day into wearing this sensor I wake up to a notification that her sugar is 66. I wake her up prick her finger and its actually at 177. Calibrations are never accepted after this point and we had to try another sensor. The sensor after this one tended to mostly stay lower than her blood sugar test by 10-40mg. Current sensor is wildly inaccurate again.
