Gergen et al. 1992. Authors studied people and reactivity to various allergens to see if a relationship exists between specific allergies by skin test and allergic rhinitis, asthma, chronic rhinitis or sinusitis. It was found that the greater number of positive skin test reactions were associated with allergic rhinitis. In addition, asthma was found to be related with dust mite and Alternaria allergy. Allergic rhinitis was related to ragweed, ryegrass, dust mite and Alternaria allergy.
