Methacholine Challenge Testing
Methacholine Challenge Testing (MCT), sometimes referred to as bronchoprovocation testing, tests how reactive and responsive your lungs are. During the test you will be asked to breathe in doses of a drug called methacholine, which triggers controlled narrowing of the airways. From here, we evaluate the degree of reactivity by performing breathing tests.
MCT is effective in diagnosing asthma.
