So I took up the Accu-chek offer and got a free Aviva meter and strips.
It is reading anywhere from 10-30 mg/dl higher than my two Ultras (one is an Ultra 2, one is a plain Ultra.) So I'm either 118 (Aviva) or 90 (ultra 2) or 85 (Ultra) .
Not a trivial difference!
Both meters test fine with control solution and the Ultra 2 is, as usual, right in the middle of the given range. Both the Ultras are old but I have bought them new batteries recently.
The last time I had an Aviva it read 240 mg/dl when I tested at 203 mg/dl at the lab (this was back when I was trying to convince my doctor I was diabetic.) At that point I ditched it. My ultras were close to the lab result when I tested.
My A1cs are always higher than I expect based on the Ultra readings so it isn't out of the range of possibility I'm running higher than I think. But the Ultra has a good rep and is consistent.
So which one to believe? My doctor no longer orders fasting tests for me, so I can't check the meters against lab.
I REALLY hate distrusting my meter this way.
Any one else run into this problem? Has anyone here lab compared the Aviva and seen a good match?
