Complementary tests in respiratory allergy

: Several complementary tests are currently available for the diagnosis and evaluation of allergic respiratory disease. Besides the classic skin prick tests which have been standardized, a number of assay methods have been developed for specific IgEs and different mediators as well as multiple tests for allergy screening. In the near future, several techniques for measuring allergens in the environment should become available for physicians and patients. The purpose of this review is to present the different complementary tests useful in respiratory allergy defining the contribution of each test in the management of patients with allergic disease.
