A bronchial challenge test is a medical test used to assist in the diagnosis of asthma. [1] The patient breathes in nebulized methacholine or histamine. Thus the test may also be called a methacholine challenge test or histamine challenge test respectively. Both drugs provoke bronchoconstriction, or narrowing of the airways.
Methacholine is primarily used to diagnose bronchial hyperreactivity, [1] which is the hallmark of asthma and also occurs in chronic obstructive pulmonary disease. This is accomplished through the bronchial challenge test , or methacholine challenge, in which a subject inhales aerosolized methacholine, leading to bronchoconstriction .
The specific inhalation challenge (SIC) is a diagnosis tool to assess airway responsiveness to "sensitizing" substances as opposed to nonspecific stimuli such as pharmacological agents (i.e. histamine, methacholine), cold air and exercise. [1]
Medication challenge tests, such as the methacholine challenge test, have a lower sensitivity for detection of exercise-induced bronchoconstriction in athletes and are also not a recommended first-line approach in the evaluation of exercise-induced asthma. [13] Mannitol inhalation [14] [15] has been recently approved for use in the United States.
