Growl. I started the Medtronic 630G last month, and just recently added their CGM to the mix (I was told the only way to get the free upgrade this summer was to purchase the whole system together…). The first day was actually pretty decent as far as accuracy goes. I like the Guardian because it’s flatter and doesn’t catch on things as much as the Dexcom. But, alas, that’s not really the important thing, is it?
It’s been 3 days and the accuracy SUCKS. I’ve followed all the rules exactly as far as when and how and what to calibrate. I’m still using the Dexcom at the same time for comparison and…I thought maybe the Guardian would impress me and be better. Yesterday, Mr. Pump said 89 flat - cool, I like that number. Mr. Dex was howling at me saying 54 and trending down. I don’t feel low. I check anyway. Yup - 51.
Honestly, if it would have been the highs that were a little off, I can deal with that. If I’m high, I’m high . As long as it’s not like super high. But this low? Mr. Pump should have buzzed and went crazy and maybe even suspended if I agreed to that.
I’ll keep going. I’ll keep using both until I run out of Dexcom life. But I’m scared to just have this Guardian guy by itself. I could pretty much trust Mr. Dex. I have zero faith in the Guardian. And, jeepers - the time it takes to calibrate this sucker. What the heck. If it’s gonna take up to 15 minutes to calibrate, I think it should maybe be a little more accurate.
I’m hoping with the new pump, they’ve obviously made some adjustments. Does anyone have any experience with insurance covering the pump (I would not order any more supplies for the CGM part) plus the Dexcom separately? I’ll contact them today about it, but I’m interested to hear anyone else’s thoughts.
