After the problems that I have been having with my G4 recently and especially after my horrible first sensor after the update, I have had a couple of conversations with Dex Techs in the last couple of days. I called them Saturday and they are replacing a couple of sensors. They had me send in data and the Tech Rep for my case called me yesterday and today.
I am now using a sensor from a different lot number and my results are more in line with what I expect. So I think that my problems have been sensor-related, not equipment or software-update related.
Tonight the Tech Rep told me a few things that I have never been told before about calibration. He suggested that when I do my two start-up calibrations that I separate the BG tests by a couple of minutes. I have always done them one right after another.
He also indicated that if I get a prompt for a calibration and my Dexcom is very close to my meter that I don’t need to enter a calibration. I’ve read of people who have ignored calibration prompts as long as their Dex is tracking well, but I have never had a Dex Rep tell me that.
So two new calibration hints for you guys.
