Allergen, Epidermals and Animal Proteins, Duck Feathers IgE
Also known as: DUCKFEATH
Use
This test aids in the detection of allergen-specific immunoglobulin E (IgE) antibodies to duck feathers. Such antibodies are indicative of a hypersensitivity or allergic reaction, which may manifest as respiratory or skin symptoms. Determining the presence and level of IgE antibodies can help in diagnosing allergic conditions, guiding dietary and environmental adjustments, and planning allergy-related treatments. However, IgE levels may not directly correlate with clinical severity or response to allergens.
Special Instructions
Avoid multiple patient encounters as much as possible when collecting specimens for allergen testing. This test is New York state approved. Please refer to 'Allergen Specimen Collection Instructions' for details when multiple allergen tests are ordered.
Limitations
Results with allergen-specific IgE levels of 0.10-0.34 kU/L are for specialist evaluation as clinical relevance may be uncertain. Despite trends correlating higher IgE levels with increased allergen sensitivity, these levels do not necessarily predict the degree of allergic reaction or skin test outcomes. It’s vital to consider the entire clinical context including patient history and specific in vivo reactivity. A negative result does not exclude the possibility of an allergy or even anaphylaxis.
