The diagnosis of pollinosis is established on the basis of typical clinical manifestations of the disease in the spring and summer. Rhinoscopically, pale or bluish color of the nasal mucosa, enlargement of the inferior turbinate are determined. The presence of clinical and anamnestic signs of pollinosis is the basis for an allergological examination (carried out outside the pollen season). Since, regardless of the place of synthesis, allergen-specific IgE antibodies are evenly distributed in the skin, nasal mucosa and serum of patients, endoprosthetic or conjunctival provocation tests (as indicated), prick test and skin scarification tests, determination of specific IgE are carried out. During an exacerbation, a large number of eosinophils can be determined in smears of nasal secretions, persistent eosinophilia of peripheral blood (12% or more).
Thus, diagnostics of pollinosis and associated allergic dermatitis, bronchial asthma is based on the seasonality of exacerbations, rhinoconjunctival syndrome appearing during the flowering period of plants, the occurrence of attacks of spasmodic cough or suffocation during walks in the countryside, in the field, in the park, forest; aggravation of symptoms in windy weather (increased circulation of pollen in the air); an increase in eosinophils in the peripheral blood, eosinophils in the cytogram of nasal secretion, in smears-prints from the nasal mucosa and conjunctiva. Etiological diagnostics is based on taking into account the seasonality of exacerbations and the calendar of flowering of plants characteristic of the corresponding region, conducting skin tests in the conditions of an allergology office during the period of remission of the disease.
