Provocation test, nasal

Method for recording a clinically current sensitization to inhaled allergens (e.g. house dust mite allergy). This makes it possible to differentiate it from a clinically silent sensitization.

Application of an aqueous allergen solution into a nostril, e.g. by means of a dosage aerosol or as a soaked cotton ball. In sensitized patients sneezing irritation and rhinorrhoea occur within a few minutes ( sensitization). Perform a negative control with the dilution solution before. Objective evaluation is performed by measuring the amount of secretion produced and the flow conditions in the nose (e.g. by active anterior rhinomanometry).
