| 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 flushings can be very frustrating because they may reflect nonspecific inflammation and may not contain diagnostic features.
