Allergen skin-prick tests to the common airborne allergens were performed on 534 children with asthma. A positive reaction to one or more allergens was observed in 81%, and the prevalence increased with age. The specific allergen reactions were characteristic with a high prevalence of reactions to house-dust mite (Dermatophagoides pteronyssinus) (88%), house dust (79%, and cat fur (62%), and a low prevalence of grass-pollen reactions (12% to 25%). We found that the diagnosis of atopy could be made in virtually all (96%) of these children by using only three allergens: D. pteronyssinus, cat fur, and rye grass.
