It should be noted that for cytological examination, material obtained via a nasal flush or biopsy is preferred to nasal secretions, which may not contain the organism.

Nasal flushings can be very frustrating because they may reflect nonspecific inflammation and may not contain diagnostic features. Client education regarding the possibility of a nonrepresentative specimen and the possible need to progress to nasal biopsy is recommended. <br><br>

Nasal biopsy specimens taken from multiple locations may be needed and aggressive sampling is recommended to obtain specimens that will give the clinician and pathologist confidence in making a diagnosis.
