Hmm...well, I'll ask the doctor which genetic testing we had done when we see him again in a couple weeks. I'm confused about that whole thing. I guess I am really hoping the sweat test was right, as I wouldn't want him to have CF. The doc we are seeing is a GI doctor, is there another specialist who usually works these things out? Most of my family is pressuring me to get a 2nd opinion for Isaac since we've been working with this doctor since September and we still don't know what's wrong. I just hate to have to explain everything all over again to a new doc and poor Isaac has seen so many doctors already.
