Introduction. Anaphylaxis is a systemic potentially life-threatening hypersensitivity reaction featuring the rapid onset, manifestations of the respiratory tract and/or hemodynamics and usually, but not always, accompanied by changes in the skin and mucous membranes [1]. The cause of developing an acute generalized reaction in food anaphylaxis may be the minimum culprit product amount that has entered the patient's body through the mouth or through the skin/mucous membranes. Patients like these are, as a rule, first seen by a paediatrician, a related specialist, or a paramedic. Since the doctors often consider the symptoms of foodborne anaphylaxis separately, the latter does not cause proper suspicion: angioedema and/or acute urticaria accompanying rhinorrhea, acute bronchospasm or laryngitis developed extremely quickly or immediately after contact with an allergen.The aim of the work was to acquaint paediatricians and doctors of related specialties with the food anaphylaxis symptoms, to justify the need for an allergologist-immunologist to consult these patients in order to resolve the issue of required component-resolved diagnosis of allergy and development of an individual elimination diet, taking into account the patient's sensitization profile.Materials and methods. Clinical observation of a child (boy, age — 12 months) with symptoms of atopic dermatitis and episodes of food anaphylaxis in the anamnesis; general clinical examination and allergological examination of the patient by component allergodiagnostics were performed.Results. Sensitization to ovalbumin (Gald 2 -16.60 kU/l) and ovomucoid (Gald 1-9.01 kU/l) was established. The detected sensitization is a predictor of severe systemic allergic reactions to eggs.Discussion. Component diagnostics performed as prescribed by an allergologist not only confirms the causative allergen, but also evaluates the risks of developing acute reactions if the allergen is accidentally introduced to the child and the timing of the patient's tolerance formation. This sensitization will cause sudden systemic allergic reactions for years to come.Conclusion. It is important for a specialist to timely suspect food anaphylaxis, differentiate it from other emergency and urgent conditions, and give the patient the correct recommendations on the need for consultation with an allergologist-immunologist. Only a thoughtful, comprehensive medical approach to each acute condition in a child will significantly reduce the risk of repeated episodes of food anaphylaxis.
