Then switch back ally ..... and test with both ....
Do not believe differences.
Mike - I think provided Ally's trends mirror each other, with each meter, I don't think there is any value in testing using both meters together. That's an eensive luxury I don't know necessarily tells Ally anything.
I make that statement as someone still working through the "batch 44" strips. I may not like the numbers, but provided my rises and trend curves reflect earlier results, I have to be happy, for the time being.
I believe ally receives (insufficient for every day use) strips for her Accu-check meter on prescription, but pays for the additional Codefree strips she needs. Her approach of stock-piling the Accu-check strips to give a meaningful period of testing seems to make sense, rather than switching back and forth every couple of weeks.
@ally1 - please correct me if I misunderstand your strip situation.
