[Experiences with a standardized acetylcholine test in occupational medicine]

This review deals with methodological features and the corresponding argumentation of a screening test for non-specific bronchial provocation with acetylcholine as it was standardized in the eastern part of Germany. This test has shown its suitability, whereby it has to be mentioned critically that the low provocation dose detects only higher grades of hyperreactivity. On the other hand the relevance of the test could be proved especially in occupational health follow-up studies.
