Bronchial Provocation Study


The purpose of the inhaled bronchial provocation study using PROVOCHOLINE® is to determine how responsive (or irritable) your airways are and to determine the severity of asthma, if present.


You’ll be asked to inhale a mist containing different concentrations of PROVOCHOLINE®. The mist is produced by a device called a nebulizer, and you’ll inhale the mist through a mouthpiece. Before and after testing begins, you will be asked to blow forcefully into pulmonary function testing equipment. The test may take up to three hours to complete.
