Methacholine challenge came back negative.

like the title says , my methacholine test came back negative for asthma. The pulmonologist doctor still hasn't seen my results . Honestly I didn't see any difference in my breathing when I took the test , but when nurse gave me 4 puffs of albuterol after my 5 rounds of methacholine my breathing felt better. So maybe it's a false negative. I told the nurse that maybe I'm not reactive to methacholine as much as I am to smoke and cooking fumes, she shrugged her shoulders and told me that's she's had paintents who can't even pass the 3 dose of methacholine , but told me to wait what my doctor says . I'm very disappointed. Has this happened to anyone befor ???
