So I've been given a remedial to take the MCT and I was wondering what the test is like and what to expect. Also, has anyone else here taken the test?
 
Here's a great way to find that answer...

Essentially you will breathe a nebulized drug that causes airway constriction. The dose that causes your airway constriction to exceed a threshold will determine your level of airway hyperreactivity, and thus determine the extent of your asthma.

My son took the test. In his experience it was not that bad. The only advice I would have for you is to follow the directions very carefully. He had to go back for a second test as his results (post inhalation) were too good...meaning he actually improved after having inhaled the irritant, indicating that his baseline should have been higher (or "better") initially. The second time he was more careful to really, really follow the techs directions. He passed. :smile:

It seems silly that this test can have such varied results in one patient, but it did. I wish you the best!
 
One piece of advice:

Ask the health care provider who performs this test to send a copy to your physician. This will be put in your medical file and become a part of your civilian medical records.
Also, when the test is completed they likely will not interpret the results for you. When you personal physician receives the results he can interpret them for you and advise you how this relates to your general health.

Of course, your personal physician's interpretation is not an indication as to whether or not you will receive a waiver. This comes from the waiver authority after they examine the test results.
