In brief, I presented to perform a methacholine challenge test.

I don't suffer asthma! I am physically fit do lots of sports involving lots of running and physical exertion.

I never have shortness of breath nor do I have any of the usual symptoms expressed by asthma sufferers.

Just failed the metha test. Why?

I had the flu just prior and a sore throat on the day. A week before I scored 120% on the spiro test.

Any thoughts, ideas, reccomendations.

Thanks
