Summary
Bronchial hyperresponsiveness consists in excessive response to bronchial stimuli.Bronchial
challenge test is used to confirm/exclude asthma (metacholine or histamine).Protection are
used to avoid passive exposure of the technicians performing the test, despite the absence of
evidence that they could develop a bronchoconstriction even if they suffer from BHR.The
purpose of the study is to determine if patients with a high level of bronchial
hyperreactivity and exposed passively to histamine during a bronchial challenge, are
developing a bronchoconstriction, when placed in the same conditions that the technicians
performing these tests.
