Latent allergy or a low exposition?

The results of a skin-prick test and statements about the season of allergic health problems were sampled from a group of 154 patients suffering from pollenosis. Then a pollen calendar was chosen on the base of literature and the statements of patients were compared with the test results and the pollen calendar. In many cases the patient had a positive test response although he stated his season of allergic troubles in a time interval which was disjoint with the blossom season of the plant the pollen of which effected in the test as the allergen. We ask, whether this responses classify as an appearance of a latent allergy or as a "normal" allergy which did not appear in consequence of the patient's low pollen exposition. On the base of our empirical material we prefer more the first alternative and assume that the "problematic" positive test responses were evoked by virtue of the patient's allergic dispositions and by his strong contact with allergens (pollens) which are correlated with the "problematic" ones.
