Differences in Meters

I know this is a noobish question, but here goes:

I was recently in hospital, and tested with both my meter and the one at the hospital. Theirs was consistently 20 points higher than mine. I’m kind of worried now that I’m letting my sugars run too high because I think my meter is accurate. How can I tell if mine or theirs was right? What should I do?


the best way to judge is to take your meter in with you when you get lab work done and when you get back your lab work compare to your meter. then you’ll always know. meters generally waver 20+ points up or down. once you know the accuracy, you can always judge by that.
