Testing once a day, in your case, will not provide you with adequate data
to learn what is causing your
blood glucose to elevate. This is the testing regimen first time users must perform before they step down to once a day or even once a week testing. The latter takes months and in some case years to get to. Until you make lifestyle changes - proper nutrition, maintaining normal weight, perform daily physical exercise - you will continue testing 6-7 times a day, or more.
