[Immunological examination methods for the diagnosis of allergic rhinitis (author's transl)]

Only a great number of well-established test methods helps to prove for sure the occurrence of allergic rhinitis. In addition to skin and provocative tests immunological laboratory tests are indicated for reliable diagnosis purposes. According to the immunological tissue reaction underlying the allergic rhinitis the following methods are suitable: the proof of histamine release of leucocytes, the determination of the immune serum globulin E-level and the differentiation of the specific IgE. Precipitation reactions prove the occurrence of antibodies of the type IgG. Hemaglutinating antibodies generally demonstrate the patient's inclination toward allergic reactions. On the basis of these investigations the specificity of the anti-allergic therapy can be essentially increased.
