Validation of the Global Allergy and Asthma European Network (GA(2)LEN) chamber for trials in allergy: Innovation of a mobile allergen exposure chamber

摘要

Background: Field clinical trials of pollen allergy are affected by the impossibility of predicting and determining individual allergen exposure because of many factors (eg, pollen season, atmospheric variations, pollutants, and lifestyles). Environmental exposure chambers, delivering a fixed amount of allergen in a controlled environmental setting, can overcome these limitations.
