3. Have a confirmed diagnosis of cystic fibrosis (by two established methods, e.g. positive sweat chloride value ≥ 60 mEq/L, nasal potential difference test, and/or genotype with two identifiable mutations consistent with CF, accompanied by one or more clinical features consistent with the CF phenotype).
