ABSTRACT
The need in study and interpretation of eosinophilograms in children with allergic diseases is conditioned by higher rate of eosinophilia, large specter of morphologic and functional signs of eosinophils, dependence of indicators from character of clinical course of disease, presence of complications and schemes of treatment. The level of laboratory techniques applied in routine clinical practice to evaluate morphological and functional characteristics of eosinophils is not developed enough. The implementation of such modern high-tech techniques as computer morphometry, highly sensitive and highly specific modifications ELISA, which are applied to detect associated with eosinophilia cytokines, chemokines and growth factors make it possible to approach to this issue at the new qualitative level.
