annonymous- it is NOT silly at all to wonder! My son could well be a 'salty' carrier himself. His sweat test was only half of what his sister's was, but his 54 is much higher than some kids here who have clear-cut CF so it can clearly go either way. I'd much rather believe he's a carrier and it drives me insane that there are several ways we are looking at that would basically confirm a cf dx for him and no real way to 100% rule it out, short of discovering Emily's 2nd mutation.
If you are interested in hearing how his story plays out when he gets further testing I'll try to keep you posted. At this point Hopkins for a workup, including nasal potential difference testing... is supposed to be our next stop, provided we can get insurance to go for it. This was on the recommendation of Emily's clinic, which doesn't like the 'limbo' state anymore than we do, but doesn't know what else to do for him.
