Glucose Meter reliability
Community Member April 17, 2007
I just discovered that there can be a big difference in the result from different glucose meters. I have a very well known name brand meter that I rely on. When I would go to my Dr. and they would use their meter, it was alway 20-40 points higher then what I had just read on my meter. After the last visit, I went and got the same brand meter as my Dr. and sure enough, I regularly is 20-50 points different then my original meter.
The one used at my Dr.'s office is a store brand and signifigantly less expensive then my other meter. Last night I dedided to put it to a test.
In a matter of 2 minutes, I tested my blood sugar on six different fingers, always getting a much different result. My old meter differences were a matter of 5 to 12 points, but the meter that I had just purchased differences were from 9-43 points different. The new meters results were always in the higher range. SO, how do we know what is reliable? I am going to assume my older meter is more accurate as it is a very expensive brand name meter, but even then there were differences in my little test. I just don't know how anybody knows if these things are accurate.
Anybody else have the same kind of differences?
