Method

FEIA (Fluorescence Enzyme Immunoassay, ImmunoCAP (Solid-phase Immunofluorescence)) – quantitative determination of specific IgE antibodies.

Description

This test detects the presence and amount of specific IgE antibodies to allergens from processed sheep wool. It helps diagnose allergic diseases related to wool contact and identify the risk of allergic reactions and anaphylactic conditions.

Indications

Diagnosis of allergic reactions to sheep wool.
Assessment of sensitization level and allergy risk.
Monitoring the effectiveness of ongoing therapy.
Evaluation of reduced sensitization after avoiding allergen contact.
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 30 minutes before the test.
For children under 1 year – fast for 30-40 minutes; for children 1-5 years – fast for 2-3 hours.

Clinical Significance

Allergy to sheep wool is rare. Skin irritation from wool contact is more common. For those with increased sensitivity, it is recommended to avoid direct contact with wool, for example, by wearing a cotton layer under woolen clothing. If there are no skin reactions, allergy is unlikely. If symptoms persist, consult an allergist for precise allergen identification.

The term "wool allergy" encompasses reactions to animal epidermis, substances used for cleaning and dyeing wool, and dust mites living in wool products. A particularly common allergen is lanolin – wool wax used in cosmetics and medicinal products. Allergy to cosmetics and woolen items may indicate lanolin allergy.
