Do all asthmatics with atopy have atopic asthma?

Because not all known allergens were included in the panel of 19 allergens, and because the test results could have been negative at the time of testing due to the absence of allergen exposure, some nonatopics may be misclassified. [...]it would seem unlikely that the use of subject-reported, doctor-diagnosed asthma as opposed to a clinical assessment or medical chart review would change the main finding of this study, which is that a large proportion of asthma patients with atopy do not have atopic asthma.
