Diagnosis of PCD in Australia
What tests are used, what to expect, and where specialist diagnostic centres are located.
Pathway after diagnosis
Children with PCD are usually referred to a specialist hospital clinic. Care often involves a respiratory specialist, ENT specialist, and respiratory physiotherapist, working with your local team.
How is PCD diagnosed?
• Nasal nitric oxide (nNO) – a screening test usually for people aged 4+ (low nNO may suggest PCD).
• Nasal brushing – a quick, scratchy swab-like test to collect cilia from the nose for detailed analysis.
• High-speed video microscopy – examines ciliary beat pattern and function.
• Electron microscopy and/or immunofluorescence – checks the internal structure of cilia (results may take weeks).
• Genetic testing – can help clarify the diagnosis but may not always be covered by Medicare.
Note: In a small number of people, current tests may not confirm PCD even when symptoms strongly suggest it. In these cases, care may proceed as for confirmed PCD while diagnostic techniques continue to evolve.
Costs and coverage
• Specialist diagnostic testing is covered by Medicare.
• Ask your team about genetic testing options and potential costs.
