The test measures the level of immunoglobulin E (IgE) antibodies specific to egg yolk in a person's blood.
Someone would have this test done if they have a suspected or known allergy to egg yolk. IgE antibodies are produced by the immune system in response to allergens, and elevated levels of IgE specific to egg yolk indicate an allergic reaction to egg yolk proteins. This test helps in diagnosing and monitoring egg yolk allergies, guiding treatment decisions, and assessing the effectiveness of allergy treatments.
