A test for objective diagnosis of nasal hyperreactivity.

The aim of this study was to develop a method for the objective diagnosis of nasal hyperreactivity. The method should be standardized and simple enough to be used in clinical practice. In the study nasal challenge test with histamine was performed. Ten healthy volunteers and ten patients with a history of nasal hyperreactivity entered the trial. Recordings of nasal mucosa congestion were made with rhinostereometry. The results indicate that this method can indeed be used for the objective diagnosis of nasal hyperreactivity.
