I was very excited when I finally got my dd on a pump and thought she would have much better control but since being on it, her sugars seemed to swing dramatically. I was horrified when I took her to the Dr today and her A1c was high (9.6) The Dr. seemed to blame it on her machine being inaccurate. She had been using the BD Machine that came with and read to her pump (the Minimed 522). He gave us a OneTouch UltraSmart and said it was more accurate and that we needed to switch although I feel he is a bit biased since he has a pump by Accucheck as well as the machines (he's diabetic too). After we got home I thought I would try the 2 machines side by side before I gave it up, and see what they would both read. At first they were reading within 10-20 of each other but then I decided to retest with the same finger to see if they would be within range of themselves. Well the Ultra was within 15 of the 1st reading while the BD was 90 off! I'm pretty upset to say the least. The Ultra seems cool and all but most of what it does our pump already does and I feel like it is overkill. I can't be expected to enter data into the machine everytime I check her (or me). That is why we got the Minimed, so we wouldn't have to enter data in and it would calculate everything for us. I guess this is more of a rant than anything. Which machines are accurate though? The UltraSmart is just too much for us. We just need something small that will give a reading and maybe have memory in it.
