Histamine provocation/unspecific bronchial provocation test
If patients don't show any pathological results in the lung function tests but report a medical history of disturbances of the airways, a well-defined (harmless) bronchial irritation can detect such alterations.
This test is also used to control the success of an inhalative therapy.
It is carried out by doing repeated lung function tests before and after the application of irritant substances.
During the tests a feeling of tightness of the chest and some hoarseness can temporarily occur.
