An asthma test evaluates lung function by measuring the ability to breathe into an instrument. Blowing into a spirometer measures the volume of air taken in and released. Additionally, a methacholine challenge test involves breathing in a potential asthma trigger – methacholine – to measure narrowing of the airways.
