[Antigen spectrum of allergic rhinitis (author's transl)]

The results of 10.000 individual tests have shown that it is necessary to revise and supplement the influences and the emergence of new antigens support this demand. Refined testing for grass pollen seems to be of particular importance, whereby cross reactions must be taken into account. The test program we must, furthermore, take into consideration the geographical incidence distribution of trees and herbs. In Austria, a considerable amount of ragweed pollen has recently been ascertained to be a cause of pollinosis and asthma. The grain pollens are of great importance and so is household dust, which contains regionally different antigens. Animal hairs and epithelia must be tested if the case history indicates possible involvement of these factors. Special mention is made of the increasing significance of mold spores and bacteria. The variety of listed antigens, each of which may cause allergic rhinitis, shows the importance of supplementing the Hansen test. The new priorities in the test programme are incorporated in, and juxtaposed to the Hansen scheme (see Table 1) for clarification.
