[The expiratory second capacity of the nose--a new method to check the intranasal provocation test].

There are several methods presently in use serving to check the result of the intranasal provocation test. There are simple procedures such as rhinoscopy and cotton swabs as well as technically more cumbersome ones, such as rhinomanumetry. The FEV1 of the nose is a simple method used to evaluate the intranasal provocation test. The results obtained after allergy exposition are objective and reliable. This technique is equally as good as the above mentioned ones, and is not as expensive.
