Under the conditions of an increasing ecologically unfavorable situation and the increasing influence of a large number of anthropogenic influences, the resistance of the child's body decreases, which inevitably manifests itself in an increase in morbidity [5]. In recent years, the so-called eco-dependent states, which affect the nature of the course of many pathological processes, have been allocated to an independent group [1,2]. Thus, more and more often, inflammatory processes in children are initially low-symptom, without causing a real danger, but later on, the manifestation of the disease, which threatens the child's life, quickly occurs [4]. Therefore, the tactics of prenosological diagnostics based on the development of new sensitive indicator systems for testing health reserves is acquiring special relevance.
