Well I just took my bg on my left hand and it was 4.8 and then on my right hand and it was 5.2. Now I know that a bg meter is not 100% accurate so I am thinking that maybe you need to have it tested against your lab results. It may be that the meter is just not giving accurate results.

3mmol difference is quite large and in fact neither reading may be accurate..should check that out with the control solution and then with the lab.

Anita,
Well you blood is circulating and yes the muscle that are working take up more glucose that the inactive ones but they take it up from the blood stream as it passes, therefore its circulating...so I am guessing over your entire body there shouldnt be a large difference in bg levels. Your body has to maintain a bg level of 5 mmol for normal cellular functions.

I could be wrong but thats what I am guessing.
