To confirm asthma if it's suspected, docs can do a methylcholine challenge as part of the PFT. The drug is a known irritant and is positive if your lung function drops by 20%. If no drop, you're considered negative for asthma. . It was part of my intial PFT appointment and perhaps yours.

Prior to this test, it was my understanding that you had to be off of any and all inhaled steroids. So in other words, if you’re being treated for asthma and take Symbicort, for example, you’d have to stop that for two weeks prior to the test, which could be a problem if you have asthma! Is this your understanding?
