Method

FEIA (Fluorescence Enzyme Immunoassay) – a fluorescent enzyme immunoassay that allows quantitative determination of sensitization levels to duck feather allergen.

Description

Direct or indirect contact with bird allergens, particularly duck feathers, can cause sensitization of the body. Bird allergens are a significant component of household dust and can trigger various allergic reactions. The test helps detect the level of specific IgE to duck feathers, which is important for diagnosing allergic conditions.

Indications

Diagnosis of allergic reactions related to contact with duck feathers.
Assessment of sensitization level and risk of developing allergic symptoms.
Monitoring the effectiveness of allergy treatment.
Evaluation of sensitization level after avoiding contact with the allergen.
Assessment of immune system status.

Preparation

Blood should be drawn in the morning on an empty stomach or 4 hours after eating.
Drinking plain still water is allowed.
Do not smoke for 30 minutes before the test.
For children under 1 year – refrain from eating for 30-40 minutes before the test; for children aged 1-5 years – 2-3 hours.

Clinical Significance

Contact with duck feathers, epithelium, or droppings can cause asthma, allergic rhinitis, conjunctivitis, urticaria, angioedema, and gastrointestinal disorders. Sensitization is common among poultry workers and bird enthusiasts. Detection of specific IgE helps diagnose occupational asthma and allergic rhinitis related to feathers. The test is important for timely diagnosis and therapy monitoring, as well as for preventing severe complications such as allergic alveolitis (hypersensitivity pneumonitis).
