Yes, this whole matter of meter inconsistency has been driving me crazy. For three months my fasting appeared to be rising, ending up in the 120s and 130s. Since I'm only pre-diabetic, I needed to know if I was crossing the line. I changed strips, I changed batteries, I changed meters. Now I'm still confused.
At one point, the new meters were showing such low fasting numbers (90s) that I thought maybe I wasn't really even pre-diabetic after all. Then I cheated and even the lower-reading meters went in the undeniably diabetic range.
My fasting this morning, if you believe my new Contour USB, was 84. And it was 76 before I went to bed! Do I believe those numbers? I'll wait and see how the next cheat goes.
I called the manufacturer because I couldn't figure out how to do something and learned that this is the old model of the meter and I could get a new model for free, which, of course, I accepted

, so, in a couple of days, I'm going to confuse myself even more.
