[Experiences with the provocative inhalation test in occupationally induced allergic diseases of the respiratory tract (author's transl)].

Using simple technique we performed 1460 inhalation tests with occupational inhalation allergens. Before inhalation provocation testing all patients had been skin tested. In the case of organic allergens the inhalative test was positive in 20%, in the case of anorganic in 10%. The parameters should be measured in those cases causing immediate reaction until 30 minutes after inhalation and in those cases causing delayed reaction until 8 hours after the provocation test. A control test with the solvent is not necessary. The results of the inhalation test depend on the quality of allergen extracts.
