Get the genetics done, if you can get your insurance to cover it. From what I've read, high IRTs can be an indication of carrier CF status. It most definitely doesn't mean your child has cF, but a 27 is not a LOW sweat number even though its in the negative range. Many centers consider 30 borderline. IMO, I'd err on the side of caution -- better to know now pre-symptoms and get excellent preventative care, than to wait until possible lung damage sets in to find out. And for what its worth, my daughter is 2 and has no lung involvement and is pancreatic sufficient (so basically NO symptoms).
