简要总结
The purpose of this study is to estimate the sensitivity, specificity and positive and negative predictive values of a positive Aridol challenge with respect to a specialist pulmonologist diagnosis of asthma in corticosteroid naive subjects with asthma-like symptoms and no previous diagnosis of asthma. The comparator is methacholine provocation
