Like "I thought my monitor or the strips were bad as well. I just got back from visiting my brother who is diabetic as well and used his monitor to compare mine and we got identical readings on both monitors. So it isn't that. As far as the srips go, I just opened them two days ago and the expiration date is may 2011. My next step right now is I am going to buy another bottle of strips in case those are somehow bad. I will keep everyone updated."
