What do you do if two meters have different readings?

I have been using the ultra one touch but recently sent for the freestyle (it was free and uses less blood). However, if I use both at the same time (like this morning just to see), they have different readings.

The freestyle has my fasting at 126 whereas the one touch has me at 138. This is the 2nd time I have used both at the same time to see the difference and it is about the same distance apart. So, could one be more accurate than the other? How do I determine which is more accurate?

I was first diagnosed w/ T2 when I was in a diet study program at Pennington Biomedical Research Center in Baton Rouge, LA back in 2001. At that time they recommended I get the One Touch Ultra as they had seen it to be the most consistent in matching lab readings. I imagine they probably got all the meters they needed from everyone for free so I'm inclined to think their comment was reasonably objective.

As another poster has said, and as a One Touch rep told me herself, meter readings are not reliable beyond about +/- 10% of the reading. A reading of 120 can mean your BG is anywhere from 108 to 132, or less or more. Also, it can be astounding how much repeat tests at the same time (within several minutes) can vary depending on which finger you prick, how large the drop of blood is, and how much you move around between the tests. My experience has been don't skimp on the blood droplet size. Larger drops give me more consistent readings.

Hi also you can check your meter to see how far off it is. Use the test soultion that came with the meter and match it to the numbers on the bottle. Making sure your meters in the acceptable range. This is very important because they can be waaay off at times and you need to know this!

Pick the one you like best and can get the cheapest strips for and use it exclusively. Meters are not designed to be 100% accurate and can be as much as 20% off from your actual blood sugar and still be classed as accurate. 126 and 138 for all intents and purposes are the same.
