In my case, I am a T1D who is quite sensitive to insulin. I have a backup CVS brand meter which use the cheaper strips. My primary meter is Bayer contour next. My main concern when I am using cheaper strips is that, when testing with a glucose level above say 200, the results vary by quite a bit. This makes corrections quite dangerous at times as opposed to my Bayer contour next which gives me much more accurate results. Another issue I have quite frequently is that the cheaper strips are sometimes deceptive during hypoglycemic events. I.e., I am fasting and my CVS brand meter comes in at 85mg/dL but my body says I'm lower, check with my Bayer, 61mg/dL. I have done careful, sterile comparisons this way many times. I only rely on my CVS brand if I don't need precision. For example, I'm feeling weird and I'm not sure if my blood glucose is way out of line or if it could be another factor such as stress. To primarily rely on test strips that are not under the highest of level quality assurance is literally life-threatening. Yes, costly. Yes, my diabetes is a pain in the ass for not only myself but the health insurance companies as well. Yes, I understand the politics. No, I cannot change my diabetes. Yes, I think life is worth the cost.
