Hello there. My son, Isaac, had testing done through you company a month or two ago. My doctor said you tested for 16 or 17 mutations, I think...and they all came back negative. I'm confused because I am reading that you test for up to 100, now why would my doctor request to check for so few? My son has failed to sweat for the sweat test 4 times, and I don't know where to turn next to find out if he has CF or not. He doesn't seem to have chronic lung problems, he coughs a lot, but nothing serious. He has had chronic diarrhea all his life though. His doctor keeps saying we need to rule out CF, even after the Ambry testing came back Negative. A week ago, Isaac's GI doc perscribed Creon, and it seems to be helping a lot...should this worry me? Does the fact that the meds are working point to a CF diagnosis a little more? Any help or advice you could give me would be greatly appreciated. Thank you!
