[The reproducibility of the acetylcholine test and the effect of the respiratory flow rate].
The reproducibility of the acetylcholine-test results was controled by means of comparative investigations on 50 patients. The method of investigation render it possible with a high reliability to exclude a bronchial hyperreactivity. However, a single positive diagnose needs an additional control examination with reference to the interpretation of evidence. The different test results are caused by the biological variability of the bronchial hyperreactivity; on the other hand, an influence of variability of the minute output of breathing could be excluded.
