Sorry for all of the frustration you are dealing with! I don't really see the point in another sweat test. The symptoms and the results of the first test indicate to me to cut to the chase and get the FULL genetic screening done.
The "pediatrician that specializes in CF" that you will be seeing - is this who recommended the second sweat test? Hopefully at your office visit you can give your son's medical history and they will go for genetic screening.
Good luck and we feel your frustration. If it is CF, you will be glad that your son is getting proper treatment. He will feel so much better, I'm sure. Hang in there!
