Abstract:
According to the current classification of clinical relevance of the positive patch test reactions, the positive results of patients who are allergic to various allergens that are not responsible for the present dermatitis do not fit into the category of "relevant to present dermatitis" but should be defined as "relevant to a preceding bout of dermatitis." This seems to us inappropriate and misleading because reexposure to the sensitizing agent would quickly revert their reaction to "relevant to present dermatitis." We suggest an alternative possibility to the current division of the various types of clinical relevance, namely, "relevance to a present allergy other than the presenting dermatitis."
