This test measures the level of IgE antibodies specific to egg white in the blood. IgE antibodies are produced by the immune system in response to an allergen, and elevated levels of egg white IgE can indicate an allergy to egg white.
Someone may have this test done if they have a history of allergic reactions to egg white, such as hives, swelling, or difficulty breathing after consuming eggs. It can also be done to confirm a suspected egg white allergy or to monitor the effectiveness of allergy treatment.
