A member asked:

Would vocal cord dysfunction lead to a positive methacholine test? can the cords constrict like bronchial passages during the test if vcd is present?

A doctor has provided 1 answer
Dr. John Chiu answered

Yes: Methacholine challenge test can at times induce vocal cord dysfunction as well even though it is mainly used in diagnosing hyperreactive airways. Asthma and vcd co-exist in many cases.
