I just failed a methachole challange test. but i did not respond to the asthma medications.?
which kinds of diseases could cause someone to fail this test, but not respond to asthma medications.
Allergic rhinitis (AR), Cystic Fibrosis (CF), Congestive Heart Failure (CHF), Chronic Obstructive Pulmonary Disease (COPD), and Bronchitis can all give a FALSELY POSITIVE methacholine challenge test.
So, you could have one of these above that made you "fail" the methacholine test if you don’t have asthma.
However, you may have asthma and just aren’t taking the right asthma medications…
Or you might have a combination of problems going on, in addition to asthma. Thus treating the mild asthma does not get at the other problems (so you have symptoms despite treating the asthma).
Or, the test may have just given a wrong result (they are not 100% precise and accurate; i.e. sensitivity for the test is only 85%).
A pulmonologist could do further testing and help more…

It is actually called a METHACHOLINE Challenge Test.
