Hayden uses a one touch ultra link meter with his pump. For about the last three days of so about every other time we test I use about 4 to 5 strips to get one reading. It says error not enough blood everytime. I am a LPN and I have been dealing with his type one now for six months between the two I would like to think I know how to tell if there is enough blood or not. So I threw one bottle of strips away thinking it was the strips and everything was fine for about the first five BGs after this then it started happening again. So I thought maybe it was the meter and not the strips and we have a back up meter the same type one touch ultra link. And again for the first couple tests it was fine and now again I just went through 4 test strips to check his BG. Has anyone else ever had this problem or know what else the problem could be?
