We have been using the Accu-Chek aviva since dx in October. From my research, the meter is supposed to be pretty accurate. We started on the OmniPod today, and the readings are off by 15-20 points. At dinner the aviva says 130 and his Pod (Freestyle strips) says 115. (Lunch aviva was 171 and pod was 150). I was just curious to see the difference bt the meters, so I had him do both at the same time. 20 points seems to be like a big difference. Is it? Should I not worry about it? Just seems like if his numbers are lower, that's a big difference if his bs is 60 compared to 40. Thanks for any help.
