Report of experience with specific bronchial provocation tests in 37 subjects with a clinical history of bronchial asthma. The tests were performed with common allergens and chemical agents. There was a significantly higher number of positive BPT's with chemical agents. Comparison between skin and inhalation tests gave a statistically significant positive correlation for common allergens, while for chemical agents skin tests were always negative, even in the case of a positive BPT. These data suggest that in the pathogenesis of bronchial responses to BPT's with chemical agents, both immunological and irritative mechanisms are involved.
