I'm confused why they would do a throat culture/swab to test for CF. DD was diagnosed at birth because of meconium illeious/bowel obstruction. Her sweattest was normal -- not borderline, not inconclusive, but a low normal number. The genetic blood test showed otherwise. She was given the stool elastase test by a dietician while hospitalized, but the doctor's comment was "we already KNOW she has CF and has pancreatic insufficiency, so the test isn't needed"
I know you mentioned that your doctor was with a CF accredited clinic. Is he part of the CF team or does the hospital/clinic you're going to have a CF Clinic. It could be that the doctor you're going isn't affiliated with the CF center. We went to a hospital with an accredited CF clinic on an upper floor, but DD was in the NICU and time after time the neonatologist on call would say one thing, while the CF doctore would say something else. IMO get a second opinion.
