Meter accuracy

I was just wondering if meters can read differently for different blood types or if this idea is pure fantasy?

The reason I've wondered this is because some of the meters that other people find accurate I have not. I have found one touch ultrasmart (now discontinued), ultra easy and the optium neo accurate for me. The one touch verio for me tests high around the 3-7 mmol mark but above that it seems accurate. The contour USB which other people have found accurate, was 3 to 5mmol out on every reading I compared with the one touch ultra easy. I feel that the ultra easy and neo are accurate for me because my body feels the way the readings are. If im feeling really hypo and starting to feel pretty faint then the reading will be 3 or below. On the verio it was 6 or so.

Has anyone else found this - that some meters reflect their physical symptoms and others seem way out?

Thanks. I still wonder though, I've had 3/4 meters that give about the same result and they correspond to how I feel and physical symptoms. These are one touch ultra smart, one touch ultra easy, latest accu-chek mobile and freestyle optium neo. Then I've had the Bayer contour USB, one touch verio, and the first accu-chek mobile which all read higher in different ranges.. Because I am insulin sensitive, if a meter reads 13 instead of 10 for example and I give 2 units as a correction instead of 1, it has pretty horrible consequences for me.

I guess I'll just stick to the ones that seem accurate for me.
