bronchoprovocation inhalation test

bronchoprovocation inhalation test, a pulmonary function test performed on patients with a history of asthma who have normal pulmonary function at rest. In a specific test, the patient inhales a particular antigen while the forced expiratory volume (FEV) is measured. In a nonspecific test, the patient inhales a substance such as histamine periodically at increasing concentrations while the FEV is measured.
