The bronchial provocation test evaluates how sensitive the airways in your lungs are. A spirometry breathing test is done before and after you inhale a powder. For this test you will inhale increasing doses of a powder called mannitol.
Spirometry can show how much air you can breathe in and out. It also shows how fast you can breathe in and out. The spirometry results are compared before and after you inhale increasing doses of the powder to see what changes there are in your breathing.
A larygoscopy may be scheduled after the bronchial provocation test. A larygoscopy is often done to identify if your vocal cords may be causing you to have trouble breathing.
