Nonspecific bronchial provocation test

An inhalation provocation test of the lungs can determine or rule out the presence of an allergy. Specific symptoms: constriction of the airways (reduction of forced expiratory volume in 1 second, FEV1). This can be confirmed in a lung function test (spirometry or body plethysmography) and by observing and documenting the reaction after the provocation.

It can provide information about

  • Airway symptoms and constriction of the airways that can be caused (“provoked”) by nonspecific respiratory stimuli such as methacholine.
  • Oversensitivity of the lungs (bronchial hypersensitivity)
  • Allergies


For the provocation test, a test solution with the bronchial irritant (methacholine) is inhaled so that it comes into contact with the bronchial mucus membrane.
