I have 2 ultra touch mini meters. I had eaten some black eye peas (dried peas that I had cooked for supper with leftover ham in them) I had always heard that these dried peas and beans can really increase your BS, so I never ate many of them, but today, I had more than usual, I figured what the heck, it's new year's numbers were not all that high nearly 2 hours later, but it said 148 the first time and 128 the second time I tested. So I got out my older ultra mini and tested a third time on it and it said 124. My guess is that the true number was somewhere between 128 and 148, probably in the 130s…but this has never happened before. I rarely check twice in a row, much less 3 times, and never had a 20 point difference.

None of the test strip meters, including hospital test strip meters, are FDA approved for clinical use. The FDA warned the president of the diabetes association of this for hospital meters a couple of years ago.

it's just that in 4 years, I've never had a 20 pt difference. It has been like 10 or less. thanks I will look up the articles.

It think it's more like you never noticed it. It took me 5 years (and my meter has always been real accurate according to solutions). I've repeated my little experiment in the link a few times since and I can get a 20 point difference from hand to hand. We assume that our blood is equally mixed with glucose throughout our bodies at all times. I'm thinking that might not be the case.

Well, it sounds fine to me . . .
The home meters are accurate to + or - 20% and thoise readings fall within that.

that question comes up quite frequently here an example of this question may be found here ~ http://www.diabeticconnect.com/discussions/19...

When married to my late wife "Jem" we both had one touch meters and I compared my meter against hers. They were about 25 pts different. I wondered about it and read all I could find on the difference at that time. I came to the conclusion that I should stay with 1 meter and use that as my meter and only use it like a check against my previous BG reading. It is telling me if my BG trend is up or down and to take action if necessary if I go to low or to high, and not worry about the meter being dead-on accurate.

there is an article in Diabetes Health Magazine which explains it briefly here ~ http://www.diabeteshealth.com/read/2007/05/07...

Battery levels might make a difference ??? Maybe u checked blood from to different sites ??? I was using one touch meters for years 10 years … I just switched over to meters by Bayer which my doctor said studies have shown to be very accurate etc … Also I have a Medtronic pump that I can link with my Bayer meter , so switched over … So far so good …

I have run the batteries out of several meters in my lifetime with Diabetes. None of them did anything like that.
