Please vote in the poll below, even if only to let me know that I’m being overly anal-retentive.
I only learned recently that the industry standard level of accuracy for blood glucose meters is to be within 20% of lab results. I learned this after a doctor’s visit where I tested my blood glucose (BG) via my home blood glucose meter within a minute of my blood being drawn for lab work. I noted my BG as 82 and thought, good, right on target.
Anyway, this time, I was careful to check very close to the time that the blood was drawn and equally careful to note that particular reading. Again, my meter said 82.
My lab result was 69! This is a difference of just under 19% (((82 – 69) / 69) * 100) = 18.84%, though perhaps I should just round to 19 since I don’t really have that level of precision in the actual readings.
I was very upset by this, and not just because my doctor warned me about low blood sugars.
If my meter is consistently 19% higher than my actual lab results would be, then it is affecting my tight control of my diabetes. After all, at 82, I do nothing and am happy to be in my target range. At 69, I’d probably have a snack or at the very least suspend my basal rate for an hour, more likely the former.
So, I called the manufacturer (Abbott) and was told that the industry standard level of accuracy is within 20%. I have since told them repeatedly that I do not care about the industry standard, only about my diabetes care. I have recommended that they go against the standard, pick a tighter standard, e.g. 5 or 10 percent and then advertise that their meter is more accurate than the competition.
I believe this would be a huge selling point. Do you agree? Please vote below.
Do you have a brand of meter that you believe is more accurate than 20%? If so, please let me know which one below. Mine is a Freestyle Flash. They have already sent me a replacement Freestyle Lite. Depending on whether I use the test strips that came with it (about 15% higher than my old too high meter) or the extra strips they sent along with it (generally within about 5% of my current meter), I get very different results. I don’t know if I can trust this through multiple batches of test strips over a period of years. I had hoped that when I called back and told them about the batch that came with the meter they would tell me that those strips were recalled. No such luck!
On the up side, this is the only meter I can find that will operate at 40 degrees Fahrenheit, meaning that I don’t need to wait half an hour in a ski lodge for the meter to warm up sufficiently to do a reading. I like the meter a lot … or would if I could get more accurate results out of it.
Anyone know of a better meter? Have you tested it along side your lab tests? How close was it?
Thanks for any input.
