Nasal Lavage Study: Comparing Single Versus Multi Sample Lavages

Nasal lavage could be an integral component of assessing airway inflammation. Research into the reproducibility of cell counts is key to understanding the value of lavage results. The objective of this study is to evaluate and compare the reproducibility of a common nasal lavage technique and its variation in a sample of subjects with nasal symptoms (e.g. runny nose, congestion, sneezing, post nasal drip), and in individuals without nasal symptoms.
