| Yes, the Compact was most consistent, but it's a very small sample. I can't really hang my hat on it. That's why I'm trying to get more people to do it..increase the sample size.
It's true that testing against lab values is the gold standard, but we'd have to wait weeks or months for people to respond to that.
And you can't really rely on a single comparison of your meter to one lab value. You would know the error for that one reading but you would not know the average error unless you repeated it many times. As you can see, there is a fair amount of variation, even with the same meter, so on a single reading you could get very lucky or very unlucky comparing it to the lab value. |
