Hi Mom2Max&Charlie - How have you and your little one been? I find it amusing that you posted on the exact same topic that I have considered addressing...those blasted sweat tests! It seems that so many people on this website with confirmed CF have had sweat testing nightmares. What kind of a hairbrained test is this, anyway? I have a science major, and I think I remember you are educated in nutrition science or something like that? If sweat tests were a science experiment, they would have a serious lack of accuracy, repeatability, and precision. In fact, data would probably be thrown out left and right. I'm still waiting on my daughter's genetic test. Her sweat tests were at the high end of normal. I'll let you know the results.
