Abstract:
Broncho-provocation tests with inhaled histamine were performed in 61 asthmatics twice at a gap of 4 weeks. Ten of them also underwent a third test after 16 weeks. More than 80% of the patients had a reproducibility of response within 1 to 2-fold concentration difference. It is concluded that under carefully controlled conditions broncho-provocation tests with histamine are reproducible.
