Hi there, My daughter is almost 5 and we have been struggling with constipation for a few years now. My daughters GI had a sweat test (didnt tell us what a sweat test was for....thats a whole other story!!!) done and it came back a 56. She doesnt have ANY pulmonary problems and is never sick. As long as she takes Miralax every day she is fine. We are going in tomorrow for another sweat test and blood work. Anyone go through the same and what was the final outcome??
