Had first consultant appointment last week and got bloods done. I have various allergies so wasn't surprised when she decided to get my IgE levels checked. Wanted to know what happens if it comes back high? I realise this confirms an allergy to something but do you then require allergy testing to get to the root of the allergy? Also I realized after the appointment I forgot to tell her I had been taking an antihistamine daily for a month (advised by my gp). Would this affect the IgE reading??
Secondly can spirometry lead to a definitive diagnosis of asthma or other things? Ive had asthma all my life but my recent flare up has both been unusual and not typical of what asthma is like for me. Just wondering what the spirometry outcome might show?
Thanks for reading x
