I have been using Freestyle Lite meter and strips for the last year. This year my insurance is saying One Touch and Accu-check are now the 'preferred' brands, and so the Freestyle strips will cost more.
So.. I have an AC Aviva, and have done side-by-side tests with Freestyle meter, using the SAME BLOOD SAMPLE. I have been surprised that the Aviva was frequently 10-60 points higher (10-20%). Some times I did multiple tests on both within minutes, with similar differences. I did 25 'dual' tests, over the past week, of which only 2 were within 5 pts of each other.
I also usually 'feel' low when my Freestyle shows 60-70, and I usually have a small snack to bump up to 80-100. But the Aviva is showing 75-90 at the same point, so I'd have to re-consider at what point to correct. But my recent A1Cs have been consistent with the average Freestyle readings.
Has anyone else found differences between meters ?
If I switch to Aviva, should I then 'correct' when the meter says 80 ?
I have already confirmed that both meters are showing the estimated PLASMA BG value, as my first suspicion was that might explain the difference.
This week I'm going to compare Freestyle with One Touch. But prior to Freestyle, I had used One Touch, and when I switched, I recall the numbers were more in sync. But I was hoping to stick with Aviva, since it requires a smaller sample than One Touch, although larger than Freestyle.
