Diagnostic Procedures in Chronic Rhinitis

Abstract

Various methods of diagnosing allergic factors in chronic rhinitis are discussed. Among the procedures which aim at detecting specific allergens, i.e. skin testing, RAST, and nasal provocation tests, the last mentioned, as they are performed directly on the shock organ, have so far been found to give the most accurate picture of clinically dominant allergens and of the intensity and character of the rhinitis. However, information obtained by analysing the correlations between different procedures is not unanimous. As long as test techniques and allergen extracts have not been standardized, one particular test cannot be recommended as the method of choice.
