IgE Egg White

Laboratory assay overview

The measurement of specific immunoglobulin E (IgE) to individual components of an allergen, either purified native or recombinant, is referred to as component resolved diagnosis (CRD).1-4 This approach represents an improvement over traditional measurement of IgE to allergen extracts that contain a mixture of proteins. The pattern of specific IgE reactivity to component allergens can predict which patients are at higher risk for systemic allergic reactions versus those who are sensitized but clinically tolerant. CDR can also be used to predict which patients are at risk for more severe reactions and which patients are likely to have milder symptoms.

Laboratory assay overview

This panel tests a child for specific IgE antibodies to 5 different foods that are commonly associated with allergies. Allergen-specific serum IgE testing is considered comparable to skin testing and may be preferred in some clinical situations. However, a positive test result only indicates that a patient is sensitized to the allergen of concern. Many IgE-sensitized individuals do not develop any symptoms when exposed to the allergen. A diagnosis of allergy should only be made by a trained medical provider after conducting a thorough clinical evaluation [1]. More specific information about allergens included in this panel may be found on the Quest Diagnostics Test Directory. ⁠⁠⁠⁠⁠⁠⁠Reference 1. Bernstein IL, et al.

Laboratory assay overview

This panel tests for specific IgE antibodies to 12 food and environmental allergens that are commonly found in Puerto Rico as causes of childhood allergies. Allergen-specific serum IgE testing is considered comparable to skin testing and may be preferred in some clinical situations. However, a positive test result only indicates that a patient is sensitized to the allergen of concern. Many IgE-sensitized individuals do not develop any symptoms when exposed to the allergen.

Laboratory assay overview

This panel tests for specific IgE antibodies to 22 food and environmental allergens commonly associated with childhood allergies. A positive test result only indicates that a patient is sensitized to the allergen of concern. A diagnosis of allergy should only be made by a medical provider after conducting a clinical evaluation.

Laboratory assay overview

This test detects the presence of specific IgE against egg whites. A positive test only indicates that a person is sensitized and potentially allergic to this allergen. A diagnosis of allergy requires clinical signs and symptoms that appear to be associated with exposure to the allergen in addition to the detection of markers of IgE sensitization [1].
