As the others said, there are no answers short of the test, and sometimes even the test does not give clear answers. I remember being in your shoes, and I know the wait is terrible. It was for me. For my girls, it was a long process to a clear diagnosis. We did the sweat test to "rule CF out," and our pediatrician and specialist both said they would be "surprised" if it was CF, but we should double check. The sweat chlorides on one daughter was borderline, and the other was normal... low, even. Yet the borderline result on my older child and the clear pattern of susceptible lungs in both led to genetic testing. Even that was not clear. Both are heterozygous for D-508, which normally means they would be carriers. But they have two other genetic factors (modifiers) that mean they are in a class of kids that have 'non traditional' CF. It was bewildering to say the least.
In the end, Robert is right to say that you have to trust the process at this point, even though the waiting will be awful. If the sweat test is not conclusive and the doctor thinks there is cause, they may ask for the genetic test. In our case, our doctors were remarkably good in their advice; if they had not insisted on the genetic test, my daughters would have lost ground in terms of lung function. If it is CF, then knowing the truth early is the best weapon you have to protect and build the lungs in these early years. I am not happy that my daughters have CF, but I am grateful that we found out before their lung function could start to deteriorate.
Whatever happens, I hope you find answers, and know that we are all willing to answer questions and give support.
