The study consists of two phases. The first phase is a cross-sectional, case-control study measuring the sensitivity and specificity of methacholine challenge testing for differentiating asthmatic participants from non-asthmatic controls. The second phase is a cross-over, randomized, double-masked trial designed to evaluate the impact of high dose versus low dose inhaled corticosteroids (ICS) on bronchial hyperreactivity (BHR) in asthmatics.
