MCT: While doing a spirometry test, metacholine is released into the spirometer. Metacholine will cause your airways to spasm/constrict...IF asthma is present.
FWIW, spirometry is a test to see how well your lungs inhale/exhale.
What's the MC test like? Well, if you have asthma, this test will show it by you having some difficulty breathing. Metacholine does that to those who have asthma. If you don't have asthma, not much will happen
If I have no problems with breathing during exercise and the only thing that really causes bronchial tightness is dog fur, can I expect to pass? Yup. The dog fur thing sounds more like an allergy. If so, easy fix.
I know I can exercise, breathe normally, etc, but will a MC test be the nail in my coffin? Only if you are diagnosed with asthma.

Hey doc,
Just as a disclaimer, I hate to beat a dead horse here with the asthma thing. I've searched the forum and it's one of the most widely discussed topics on here. It seems like freaking everyone has had asthma at some point.
But, I'm not gonna ask you about "what my chances are" etc, cause I know this all works on a case-to-case basis. I just want to know a little more about the methacholine test.
I was prescribed with albuterol at eleven when my dad noticed I was wheezing after exercise. My doctor told me that I had exercise induced asthma and that I would probably grow out of it as i went through puberty. I've never had an "asthma attack" and all my asthma problems were exercise related. They made exercise uncomfortable in my early teen years, but never impossible or potentially harmful. However, I continued getting albuterol refills since this year (I'm a 17 year old senior in high school). Up until last year, I really did think I needed the inhaler (primarily during the winter--the warmer months never gave me issues) , until I exercised once without it and experienced no problems. I can run an easy four miles in 10 degree weather, snow and ice and not experience wheezing or thoracic or bronchial discomfort of any kind. I do have a slight allergy to dog hair, which does induce wheezing.
I realize that since I've gotten refills on the inhaler past age 13 that I'm going to need to get a waiver if I want to be successful in the Navy (especially aviation). This depends on my not using an inhaler for five years (which is fine, since five years will have passed since I join OCS), and my getting a methacholine test.
My question: What's the MC test like? If I have no problems with breathing during exercise and the only thing that really causes bronchial tightness is dog fur, can I expect to pass? I know I can exercise, breathe normally, etc, but will a MC test be the nail in my coffin?
Sorry if this is a redundant question...I'd just like some personal clarification.
