liz38, my son had a 12 sweat test but upon looking at his gene sequence they found 2 mutations of the CF gene. If you and your husband have been tested genetically confirm that you have been tested for over 1000 mutations. If not, then I'd pursue genetic testing for you son. If you choose not to always keep in mind that he could have cf. My son is not symptomatic. We pursued the testing because I have cf and I wanted to be absolutely sure he didn't have it. He also had negative newborn screening test.</end quote></div>
Just a note on this, full genetic testing is not readily available in Australia. We have to go through Ambry in the US, which is way too expensive for most of us (our form of insurance would not cover any of the costs, and the cost of sending the sample is another addition). I believe the most mutations they will test for in our labs is about 36 (someone please correct me if you know of anywhere that can do more, I would love to know).
Liz, I definitely agree that you need to keep in mind that he still could have CF. If he has any symptoms such as asthma, wheezing, malabsorption or chest infections, you should rethink the situation and ask whether he needs some preventative treatments even without a formal diagnosis.
Sorry to be a bummer, I'm very glad to hear that he probably doesn't have CF but just giving a bit of extra info!
