I am a Canadian resident, i have had asthma since I was 2 years old, I am now 27 and recently started seeing an Asthma specialist/pulmologist about a year ago. I was diagnosed with Asthma in Romania at the age of 2 and have been on puffers since I moved to Canada in 94 I am on ventolin and advair. Back in January I had a spirometry test done ordered by my specialist and it came back according to her normal she then asked me for a history of my diagnosis which I explained to her and then she started saying that she needs to find out if I do have asthma and if were not chasing down the wrong diagnosis she also said that I don't want to keep treating you for asthma if its something else. She then ordered a methacoline challenge test to diagnose, I was bewildered in 25 years of my life I have never been told once that I do not have asthma or been questioned or second guessed on it. I had the methacolic test done today, I already had symptoms going into the test as I was not able to take my puffers so I was wheezy. After they gave me the drug it aggrivated even worse and I had a hard time breathing for the test as they guided me, I don't know what the results are yet or how it turned out but she kept saying it was low and I had to keep redoing the breathing tests cause a few of them I didn't fill up the bar on the computer completley like taking my breaths. I don't understand just because I had a normal spirometry it automatically means I don't have asthma? also I read online that its not a very accurate test or specific to ashtma so its hard too diagnose it. And as well spirometry tests just because the results are normal does not rule out asthma.
