I have an Accucheck nano testing kit. Often I will get a high reading and immediatley re-check myself. Take this morning for example I tested at 7 so in a panic retested and it read as 6.5. is the level of inaccuracy normal?
My hands were washed.
I have never used an Accucheck, but in general, sadly, meters are pretty inaccurate. I suspect it may in fact be the strips rather than the meters that are at fault. OK, there are rules as to how inaccurate they are allowed to be, but who is policing them? Each time I open a new tub of strips I am in suspense, as it seems to me some give higher readings than others (I think Bluetit has remarked on this also.) I use a TEE2 and a Codefree, and like Xfieldok I test one against the other when I get a suspect reading. Or retest up to 3 times with the same meter, same drop of blood. 7 and 6.5 are not so very far apart, but I have seen eg 6.6 followed by 4.9. As a pre-prandial reading that leaves me in a quandary. Do I accept the 4.9 and cheerfully eat a meal which includes some carbs, or do I go for the 6.6 and postpone eating or at least eat just protein and fat? (in the event it may depend on how hungry I feel and how inconvenient it may be to eat later.)
Meters are a pain in the neck, but they are all we have. IMO they are better than nothing.
