Patients often show a wide range of varying symptoms and sensitization patterns against several allergens. Therefore diagnosing an allergic disease is always based on anamnesis, in-vivo testing and in-vitro diagnostics. In-vitro diagnostics in particular, i.e. the determination of specific IgE against the suspected allergens, are essential whenever an allergic response or severe reaction is suspected but furthermore also as a foundation for possible immunotherapy and its preparation. The preparation for immunotherapy requires the results of a quantitative test system like single allergen systems. These tests are expensive and need expensive laboratory equipment. With the RIDA qLine Allergy test, R-Biopharm AG has developed a sophisticated allergy in-vitro test system that combines both quantitative determination and very economic and easy handling.
