An Egg White (Anda) Individual Food Allergen test is a specific blood test used to detect an allergic sensitivity to proteins found in egg whites. Egg allergy is one of the most common food allergies, particularly in children. While both the yolk and the white contain proteins, the white is typically the primary trigger for allergic reactions.

The test measures the level of specific IgE antibodies produced by the immune system in response to egg white exposure. A positive result helps clinicians diagnose the allergy, allowing individuals to manage symptoms by avoiding egg-containing products and preventing potential reactions like hives, digestive distress, or anaphylaxis.

An Egg Yolk (Anda) Individual Food Allergen test is a specific blood diagnostic tool used to identify allergic sensitivity to the proteins contained within egg yolks. Although egg whites are more commonly associated with allergic reactions, the yolk also contains distinct proteins that can trigger an inappropriate immune response.

The test measures the concentration of specific IgE antibodies in the serum produced against egg yolk proteins. Identifying an egg yolk allergy helps healthcare providers create tailored dietary management plans, helping individuals safely avoid trigger foods and prevent allergic symptoms ranging from mild hives and gastrointestinal discomfort to severe anaphylaxis.
