I'm sorry I can't really answer any of you your questions. I've only ever heard about
1 type of sweat test, where the accuracy is about
98%. I never knew there were 2 different types!
Severe asthma can sometimes show symptoms worse than CF, so this is still a possibility for your son.
Most people with CF do not have any known relatives with the condition, as it's still really being understood, about
how it can effect people.
I'm sorry I can't give any better answers, and the only way of knowing for sure whether your son has CF is by waiting for all testing to come back. CF can be mistaken for so many different things, and even if you have a few symptoms that could indicate CF, it isn't always the case that that is definately what it is. Your other children will need to be tested too, if it is found your son has CF.
All the best of luck with everything
