Her presenterer vi en standardisert protokoll for å måle nasal potensielle forskjellen (OD). Cystisk fibrose transmembrane konduktans regulator (CFTR) og epithelial natrium kanal (ENaC)-funksjonen evalueres etter endringen i spenning over nasal epitel etter superfusion løsninger som endrer ion kanal aktivitet, gir en utfallet tiltaket.
