I'm not sure if this is the correct spot for this question I apologize if it isn't. For the last week since diagnosis and beginning to test multiple times daily I have been shearing my wife's meter, she uses a TrueTrack. Last night I finally got my own a OneTouch flex. My question, when I tested with my new meter the first time I also tested with hers immediately after and the readings were different by 59. 93 on hers 152 on my new one. This can't be a normal difference just because they are 2 different meters and brands can it? One has to be way off. This was after having eaten less than 15 carbs all day and just returning from walking 2 miles at the gym. Any ideas on this?
