Hi all. I recently changed insurance, and I had to switch away from my Freestyle Lite meters. I now am using an Accu-Chek Aviva and Aviva Nano. I have been communicating with AccuChek over an issue I am having with extremely high deviation between the AccuChek and my Freestyle and OneTouch meters.
I’ve never had a problem with any of my Avivas. I always test my blood in the car immediately after having my lab work and make a note to compare it to the lab results. It’s never more than 5 points difference.
I have started using Aviva Nano this last week (I used freestyle before this!) and my results are always higher than with Freestyle(5-34mg /dl variation so far!). Since it seems to be such a good device, I wonder if I should keep it or change back to freestyle! It is driving me nuts this difference, especially during hypos since the Aviva always reads normal or almost normal glucose levels! I am now wondering what values I should take into consideration and feeling extremely confused!!! Have you come to any conclusions so far?!
I used Accu-chek with very good reliability, and always found it one of the better meters (along with One Touch that I now use with my Ping). I've also heard that from others. But we're all different, or perhaps there were a batch or model made that don't have the same reliability. I have checked it with another meter but unless there are significant problems, I decided that for me, comparing one meter to another on a regular basis is a way to drive myself nuts, so I gave away the other meter. And I do check my blood sugar at 55 rather than "running for the glucose". I can usually recognize lows in the 50s but I don't find them "feeling like total crap". I reserve that judgement and that action (glucose before testing) for numbers in the 40s and 30s.
I'm glad AccuChek is being responsive and I hope you find a meter you feel comfortable with.
I want to write a retraction to this post. I have found that the accu-chek readings are much closer to being accurate than the freestyle strips. All other brands for example freestyle and one touch skew the results of medical trials by making it appear that blood sugars are higher than they actually are.
The user believes that the blood glucose levels are high, and thus administers more insulin. The unfortunate thing about A1c readings is that they do not reflect overall health. If your blood sugar is 300 half the time and 50 the other half, your A1c could reflect that you are reasonably healthy which of course is not true. In medical trials however the goal is not the patient's health, it is simply lowest possible A1c number which matters.
My personal A1c has improved after switching to accu-chek because I now have a better idea of what my readings are, and have less overeating due to nocturnal lows. In fact my nocturnal low problems have almost completely disappeared.
So to summarize: The Accu-Chek strips are the most accurate strips on the market, and I now use them exclusively. They are also made in USA and have great customer service who were willing to send me additional meters and strips to test.
They also have some really nice meters in europe that can be imported to the USA such as the Aviva Nano (low cost) and Aviva Expert (high feature).
One final note: If you read the fine print on all brands of strips, you find that as the blood sugar rises, the margin of error increases. When the baseline of measurement is raised (like it is on the freestyle and onetouch) it means that the range of results is narrower.This is just another example of said companies working the system. It makes their results appear more consistent because the spectrum of readings is smaller.
I read your retraction and am glad you finally realized that the Accu-chek was the better meter. I have been using Accu-chek Aviva and Compact for many years and find it to be very accurate as far as meters go. I was once given a Freestyle meter and compared it to Accu-chek and found it not as accurate as accurate. Although I'm finally giving up my Accu-cheks for Nova Max which which I compared and found it to be comparable.
I agree with you about checking all the time (I am kind of a freak about that!)! I even check when I'm 30s-40s (which, fortunatelly doen't happen a lot!) and I believe I am getting used to the Aviva! I like the fact that I can see a graphic on my computer of what has has been going on! I thank you all for helping me with your personal experience!!! ;)
