2.Diagnostic investigations

Nasal nitric oxide: as per ATS 2018 guidelines, consider obtaining nasal nitric oxide testing over transmission electron microscopy and/or genetic testing for the diagnosis of PCD in cooperative patients ≥ 5 years of age with a clinical phenotype consistent with PCD and with cystic fibrosis excluded.
