IgE Chicken Feathers

Laboratory assay overview

Detect possible allergic responses to various substances in the environment (see Test Includes) and evaluate for hay fever, asthma, atopic eczema, and respiratory allergy. The quantitative allergen-specific IgE test is indicated (1) to determine whether an individual has elevated allergen-specific IgE antibodies; (2) if specific allergic sensitivity is needed to allow immunotherapy to be initiated; (3) when testing individuals for agents that may potentially cause anaphylaxis; (4) when evaluating individuals who are taking medication (eg, long-acting antihistamines) that may interfere with other testing modalities (eg, skin testing); (5) if immunotherapy or other therapeutic measures based on skin testing results have not led to a satisfactory remission of symptoms; (6) when an individual is unresponsive to medical management where identification of offending allergens may be beneficial.

Laboratory assay overview

This panel tests for specific IgE antibodies to 5 different animal allergens 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 test detects the presence of specific IgE against chicken feathers. 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]. More specific information about this allergen can be found on the following website: https://www.thermofisher.com/phadia/us/en/resources/allergen-encyclopedia.html Reference 1. Bernstein IL, et al.
