➡️ What is a Methacholine Challenge Test?
A Methacholine Challenge Test is a type of bronchoprovocation test that is used by physicians and Respiratory Therapists to help diagnose a patient with asthma. That is the most important thing to remember about this test: It is primarily indicated to help with the diagnosis of asthma.

➡️ What is Methacholine?
Methacholine is a cholinergic drug that, when inhaled, causes narrowing of the airways in order to mimic the effects of asthma. As doses of methacholine are given, breathing tests are performed to assess the patient’s response to the drug. The test starts with a low dose of methacholine and is increased incrementally until there is a significant change in the patient’s FEV1.

➡️ Indications of a Bronchoprovocation Study:
▪ To access the risk of developing asthma
▪ To access airway hyperresponsiveness
▪ To access if medications are working

In general, when we think of a bronchoprovocation study, we’re actually referring to a Methacholine Challenge Test. The two terms can usually be used interchangeably. We wanted to create this video just to provide you with a quick overview of this topic, however, we'll be breaking it down even further in a separate video.
