Hi This is the first time I have ever posted anything on this but wanted to share something that happened. My granddaughter Cecelia DX 1/09 has been on the pump since 9/09 is having trouble with lows lately. The other night she told her Mom that she needed her jelly that her sugar was low, so they checked her to find the glucometer read 527. My daughter (who is an RN) just felt something was not right with that and decided to check her with another glucometer and that read error. She retried with the first meter and that also read error. They had opened that bottle of strips that morning and her other grandmother had a couple of readings that said error so my daughter decided to open a new bottle of strips and recheck her and she was right she was 54. After calling the company they are sending her a new glucometer and strips and she has to return the strips and glucometer she was calling about. They told her she had probably had a bad batch of strips!! I was just wondering if this was common or if anyone else has had bad strips? It is a very scary thing and it never entered my mind as her grandma/caretaker that I had to think of that too.
