title: [Comparability of jet and ultrasonic aerosols in bronchial reactivity tests].
abstract: The use of tests of bronchial reactivity for expert's opinions as well as ability examinations and check-ups in the field of occupational medicine makes great demands on their reproducibility. In the case of different application techniques the comparability of the test results is to be proved. For two aerosol producers used in the GDR test variants reliable for many years were comparatively investigated. Hereby the possibility could be proved on principle to achieve comparable results by variation of the concentration of the acetylcholine solution given. The choice of the test concentration in question is decisively influenced by the aim of the examination and the kind of test persons.
