The study includes a pre-study telephone interview with healthy controls to assess their eligibility for participation. During the study visit, a background information form and an asthma questionnaire are completed. At the study visit, a methacholine challenge test measuring airway hyperresponsiveness and an exhaled nitric oxide measurement are performed. The effect of medication intensification in asthma patients is further assessed through a telephone interview 1-2 months after the medication adjustment.
