Bronchial Challenge Test

A Bronchial Challenge Test is a procedure used to assess how reactive your airways are, helping diagnose conditions like asthma. During the test, you breathe in increasing amounts of a special substance, often a mild allergen or medication that can trigger bronchoconstriction (narrowing of the airways). Your lung function is then measured before and after exposure. If your airways react strongly, it may indicate asthma or heightened airway sensitivity. This test helps doctors understand the severity of your condition and tailor appropriate treatment plans.
