I require to prove my childhood asthma is over, my last incident was at 14 and now i just have allergies.
I’m prescribed singulair, but dont take it. Are there any tests or series of tests i can take to prove I’ve shaken it? There are numerous jobs im interested in, and I require my own papers proving im great.
Thank you.

Your doctor will send you for pulmonary function tests if this is necessary.
