I always get long winded, so here is the brief question :)

We get control liquid to verify our strips are within spec. I get it. My strips give a window of 107 - 142, which tells me its a waste of a strip to test, given that big a window, and new strips.

Where is the liquid that is equal to a BG reading which is known, that will tell us if our meters are accurate? Surely they could create a control solution that works out to, or simulates, a BG content of say, 120 that if we use on our meters, will give a perfect meter, a 120. Since there is no such thing as a perfect $18 meter, we can then get an idea of how accurate, or dependable, our meters are? Seems easy enough. Might cost a bit, but it might help the state of mind of some of us.

Meters are acceptable up to 20% accurate, and I have been told the FDA only requires 30% accuracy. Well, if that's how it is, so be it, but I am also told that any time my BG exceeds 140, especially on a spike, I am doing damage to myself. I don't see any 20% margin in that imposing 140 number. Its cast in stone, so while I have been monitoring my BG with my Ultra One Touch Mini, I have only seen a few 140+ spikes in the last three months, fasting is high 70 to low 80, and in four to five tests a day, I seem to be under 115 even after most of my meals.

This means I should be excitedly looking for my A1c test next month to come in somewhere in the mid 5's, which will thrill me to death. Of course, if I am still in the high 6's, I will be depressed, and lose all faith in my meter, so given what a valuable tool the meter is to all of us, why not a control solution with a known BG number to let us know where our meters are at?

Not a scientist. Just know what I would like to have as a weapon against this disease, and such a liquid would go a long way towards helping me control it even tighter.

The control solution is used to check BOTH the meter and test strips are working properly. The solution should be at room temperature 68-77 degrees F. Your test solution results should fall between the indicated levels as marked on the test strip vial. Mine is usually 101-134 mg/dl, sometimes I've seen as high as 137 mg/dl on the vial. Both the solution and test strips have expiration dates. Be sure you do not fall outside of those dates. I have also a backup Ultra Mini that I use along side my regular Ultra Mini. Once every 3 months (quarterly) I compare my glucose test results and the control solution results using both meters.

Thanks. I think I phrased it too poorly to make my point. The control solution doesn't do anything to prove or disprove the accuracy of the meter.

All my "dream" solution would do is simulate glucose at a level that would match a fixed number, like say 120. When I use it, an accurate meter would display 120. Any variance would give us more insight into what the meter is really capable of.

Somewhere between 107 and 142 doesn't tell me anything other than the strips are good, and to be honest, that is such a wide space, I think the strips would have to be really old, or from a very bad environment to fall outside those numbers :)

If the control solution we use now, was made to check both the meter and the strip, and it fell outside the window, is that the meter, or the strip? So you see, I think the control solution only checks the strips.

Montana? Is your username because you live there? I so love Montana. My goal has always been to wind up there, far from the ridiculous crowds that are building almost everywhere else.

Thanks much,

John
