Either of them could be correct, neither of them could be correct, both of them could be correct. :)

All meters have to conform to the same accuracy standards, and this is they must be accurate to within plus or minus 15%. That is a wide range. There are also other factors, such as a rogue test strip and human error, also our blood rushes round our body very quickly, and each red blood cell will have a different amount of glucose attached to it, so to get two identical readings requires a lot of luck, and this is even using the same meter, same drop of blood from same finger.

It is very frustrating, but it's all we have. I suggest you put one meter away and stick to the other.

@"Bluetit1802. Thanks for replying. I'm confused as to which to use as One gives low reading one higher, once I get in low 5's I get weird, one is mobile one ordinary. Don't want to over eat if I use the 4.7 reading meter. Thanks again for your help

If I were you, assuming you are not on insulin and only using it to test out food, I would use the one that reads higher. Better that way than to have a false sense of security. ;) Are you saying you eat more if your pre-meal level is low? Isn't that defeating the object of getting good control?
