The purpose of the study is to find out a correlation between the inhalation++ broncho-provocative tests and the skin allergic tests as well as a correlation between the inhalation broncho-provocative tests and the level of total and specific immunoglobulins class E. 41 patients with bronchial asthma were examined to whom 52 inhalation broncho-provocative tests with atopic allergens were performed and a comparison with the skin allergic tests with the same allergens was made. The level of the specific immunoglobulins E, reacting as antibodies towards 42 atopic allergens, was examined and the results were compared with those of the inhalation broncho-provocative tests with the same allergens. A moderate correlation between the inhalation broncho-provocative tests and the skin allergic tests and a significant correlation between the inhalation broncho-provocative tests and the specific antibodies level were found.
