Diagnostic investigations are complex, requiring expensive arrangements and an experienced team of clinicians and scientists. People with persistent respiratory symptoms such as rhinitis, rhino-sinusitis, infertility, recurrent otitis media should seek medical care and undergo further testing. Nasal nitric oxide levels are low in PCD and should be performed as a screening test. Transmission electron microscopy to assess the ultrastructure of cilia is another important investigation that can confirm the diagnosis.
