Glucose Meter Accuracy: (Please Vote) Is 20% close enough for you?

September 2, 2011

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.
