Here's a funny thing....

I recently did a blood glucose check before driving home from work, and on doing another before dinner found I had gone up not down, which , given I'd not eaten since afternoon tea break rather surprised me. Being inquisitive, I did another, and used the other hand, and got a reading in line with expectations. This got me thinking and on several occasions I checked twice, once on each hand, variations..... I have calibrated the meter, it's fine, and also used a different meter ( same model etc). I find that I get a variation of up to 4 between the left and right hand, with the left hand always being lower. Curious. Given the "below 5, don't drive " thing, which hand does one believe?. For than matter how can one's blood stream show such a lopsided glucose count?. Any ideas?. Since seen old posts on this, without a clear answer, since the difference is a very significant one in terms of insulin dose etc.

Welcome to the forum, Andrew110758. Meters are permitted a level of variation 15% if memory serves - so that could be part of the answer. 4 is a larger difference, so could one hand be contaminated with sugar from jam, hand cream etc?

I'd thought of that one, and in any case, on each occasion when I have tested, my hands are freshly washed, and the test is always before eating to find out how much to eat between meals, or to calculate a correction to the dose required by carb count. I'd guess it is a physiological thing but why?. Repeat testing on the same hand does not usually throw up a variation of more than 1 unit.
