I've had symptoms of dust mite allergy for years, and since I was diagnosed with asthma last year, the dust has emerged as a major trigger. I had allergy testing done and I'm only allergic to ragweed (which seems to have only a mild effect on my asthma, despite causing other allergy symptoms).
Could it be a false negative? Or maybe dust is an irritant for me, rather than a true allergy, like cigarette smoke or air pollution?
