At my daughters 9 month checkup our pediatrician wanted to test for CF and she brought the head of peds in and he agreed. We went for a sweat test the following week and when i called in for the results i was told they were fine only to recieve a phone call a minute later telling me they didn't recieve enough sweat and that we would have to go back. It took 2 weeks to get in for another one it was on 5/24. I called that day for the results and was told by the nurse that everything came back normal. Well this morning i recieved a phone call from the dr's office sending her on a referal to see a pulmenologist the person scheduling appt didn't know what it was for. I called back and asked to speak to my dr but the nurse called me back. She told me that her results had come back normal but borderline I asked how it was normal and borderline. I asked for the number and it was 68 and what i have seen 40-60 is borderline and 60 and above is postive. I no longer trust what the dr's office i don't belive they have any idea. I was hoping someone w/ experience could inform me on what the ranges are and if 68 is borderline or what exactly it is.
