Blown Nasal Secretion Measurements in Rhinosinusitis: Repeatability and Validity Compared to Nasal Lavage
To process blown nasal secretions from subjects with rhinosinusitis and to obtain a specimen by nasal lavage. To investigate the reliability and validity of the measurements we will determine their repeatability and compare them with those of nasal lavage in the same subjects.
