Early this afternoon I tested 5 times using my new Accu-chek Nano trying to get a handle on my blood sugar. I got these results
156 (higher than I expected)
121 (different enough that I wanted to reconfirm)
161 (OK - the higher # is probably right but to confirm..)
I know these are all 20% plus or minus something like 137 and I used 140 to correct but I never had such a repeated spread using FreeStyle. Do Accu-Chek users regularly have to deal with this level of variance?
