Duck Feather Specific IgE Test in Hawaii

What this test measures

Duck feather allergens are proteins associated with dander, saliva, and dust that collect in feathers and down products. Reactions to feather bedding and outerwear have been recognized, and symptoms often include sneezing, nasal congestion, itchy eyes, or skin irritation. Some people with these symptoms are instead sensitive to dust mites that live in bedding, which is one reason testing may include both feather and mite allergens.

The assay uses a serum sample collected from a vein. Laboratories typically report a quantitative IgE level for duck feathers along with a graded class, and the test may be ordered alone or within a panel that includes goose feathers, chicken feathers, dust mites, and mold. No special timing is required, and fasting is not generally necessary.

People often order this test when symptoms appear around feather pillows, duvets, or outerwear and they want to know whether an allergy is involved. Bedroom symptoms can also come from dust mites or other indoor allergens, so a provider may recommend a broader panel. A qualified healthcare provider should interpret results with your exposure history and symptom pattern.
