James,
I've found the same issue w/my meters showing wide discrepancies. I accidentally hit the wrong button in reading the previous response and it made it look like I thought they're remarks were helpful - they weren't. To say that you shouldn't use more than one meter to solve the situation is ridiculous - when the problem is not the use of different meters - it's the wanting to know which meter you should trust to be giving you an accurate result! I've been searching for answers to this question on the web and so far I've found 2 things [unfortunately haven't been able to check on either yet as I just found them this evening]: * They said to check what your meter's results come from - whole blood equivalent or plasma equivalent < the latter is apparently what most labs use for A1C results * Also, another source said when you have blood drawn for A1C - to ask for a drop of the blood they drew [and if they won't - immediately test right there] and use your monitor to test it ... write down the results and compare them to your A1C results and this should show how well your meter is reading. Unfortunately, I just had blood tests done and won't be able to try this 'til next testing in 4 months!
Good luck James - please let us know if you learn any more about this.
