Chicken egg (Gallus gallus domesticus) is a protein-rich food source commonly consumed raw, boiled, or processed. Egg white is considered highly allergenic. Eggs are one of the most common sources of food allergy, especially in infants and children. About 0.5-2.5% of young children in the general population have an egg allergy, while among adults this rate is less than 0.25%.
Consumption of egg white can cause allergic symptoms: gastrointestinal disturbances, respiratory symptoms, skin manifestations, and anaphylaxis. People with egg allergy are advised to strictly avoid eggs and products containing them.
Children with egg allergy are often mistakenly denied influenza or MMR vaccination due to the small amount of egg protein in vaccines, although studies confirm their safety.
Egg allergy increases the risk of sensitization to aeroallergens such as grass pollen, house dust mites, cats, and dogs.
Early introduction of eggs into infants' diets promotes tolerance development and is being studied as a primary allergy prevention method. Oral immunotherapy is also used in some countries for patients who cannot develop natural tolerance.
ELISA (EIA) (enzyme immunoassay) – quantitative determination.
