Hi Folks, Ive have been using CodeFree for a while now and Ive been getting readings in the 5s to 6s I then decided to buy the AccuChek Avia and run the tests at the same time. So far the AccuChek seems more stable with blood sugars being 0.1 0.2 different across several tests / fingers Where as code free swings 1 - 1.5 mol across fingers. I have taken my blood there and Accu Chek says I am 4.2 mmol where as CodeFree says I am 6.5 So the big question thats a massive difference so which is more accurate? I tend to believe the Accu-Chek as there are times with both meters agree but for the most part CodeFree seems least stable with results. I took 4 tests once with codefree and Got 4.2 - 7 mmol across 4 tessts with the same drop of blood. I took 4 tests with AccuChek and got 0.4 difference across all tests. Is my code free broken? Which would you believe?
