Conclusions for pollinosis: 1. RAST is not necessary for the diagnosis when history and skin tests are characteristic. 2. If RAST is indicated (e.g. small children, urticaria factitia, eczema) tests with two or three grasses or a grass-mixture are sufficient. 3. RAST classes 1 and 2 have no diagnostic value. 4. If skin tests give no clearcut results provocation tests are preferable to RAST.
