Résultats des tests cutanés dans l'exploration des toxidermies

In patients presenting adverse drug reactions such as urticaria, angioedema, maculopapular rash, erythroderma and generalized eczema, the frequency of positive tests is high in general and for each therapeutic class (betalactams, NSAIDs, RCM). Diluted aliquots for pt remained sensitive and could be useful in exploring urticaria or angioedema, in the same way as diluted aliquots for IDT in both types of reaction. Better standardization of test procedures (including diluted aliquots) and of result reading would improve evaluation of the specificity and relevance of skin tests in adverse drug reactions.
