This is excellent discussion and unfortunately I have used these meters all.
I am one of those folks whose liver decides its neat to throw the trick sugars out early for another pass back to the liver but means it gets pushed all around the body even finger tips where if there is any sensitivity of the test strips to all sugars plus glucose D one gets readings 40 to 100 points higher than the glucose D only.
My cgms has filters against that and my meter I use does a good job knocking out the trick sugars and tracks the cgms readings very well. Accu-check was the worst and this was on their ole pqq teststrips. They may have fixed by now.
I have to tell you that depending on your body make-up and what it does handling trick sugars, I would offer be carefull switching meters out. My one touch was fine as long as I always drank a gallon of water each time I tested or I would see high readings on it but it is billed as insensitive on the trick sugars. The Bayer Consul is intriguing but even though test strip is described as FAD GDH; I also saw a 40 point offset from my meter. I am not sure, but strips look like Nova Biomedical technology who make a great meter but I saw sensitivities on that as well.
Typically; I would see for the first 2 hours of digestion, all meters track great on my body, after the 2 hours I would see divergence in meters and this would last 6 hours till cracked - exhausted out of my body.
Before any changes, I would go get one of these puppies and small tub of strips and test first eating your favorite food that has high fructose corn sugar and some of the other sneaky man made sugars tossed into things and see if meter holds together through the whole 6 hour period between 2 meals prior to changing meters. The last thing a diabetic needs is a meter reading higher than it should due to trick sugars showing up intermittently and only at gut/intestine output times.
For some folks who have well behaved bodies, all/most meters are the same and accurate as done by others in review. For the rest of us who have bodies operating at the edge of hemocrit, water, oxygen ranges and throwing out uncracked trick sugars out for later passes thru liver, I would check carefully by pretesting.
The bayer console unit with its computer bus interface is very intriguing.
Lastly, Nova Biomedicals make a hospital version of their meter with two extra measuirng wells on the test strip to compenste the Hemocrit and another variable to ensure accurate readings in the hospital setting. I do not believe that it is available to the consumer marketplace nor do any other consumer grade products compensate that either as best as I know.
