Egg white IgE

The Egg White IgE test is an essential diagnostic tool for detecting specific IgE antibodies in the blood, indicating an allergic reaction to egg white. This test is vital for diagnosing and managing egg allergies, which can present with symptoms ranging from mild gastrointestinal discomfort to severe anaphylactic reactions. Utilizing the Fluorescence Enzyme Immunoassay (FEIA) method, the test ensures high accuracy by binding allergens to a hydrophobic cellulosic polymer. A serum sample is required, with results interpreted across a scale from class 0 (negative) to class 6 (very high positive), reflecting the severity of the allergy. Reflex testing for specific egg white components, like ovalbumin and ovomucoid, can further refine diagnosis and management strategies. The Egg White IgE test aids in confirming sensitization, guiding treatment decisions, and counseling patients on prognosis. It is a critical component in the comprehensive management of egg allergies, helping to prevent adverse reactions and improve patient outcomes.

Purpose of the test

The Egg White IgE test is essential for diagnosing egg allergies by detecting specific IgE antibodies in the blood. It helps identify allergens causing symptoms like gastrointestinal issues, respiratory problems, and anaphylaxis. The test uses the Fluorescence Enzyme Immunoassay (FEIA) method, requiring a serum sample. Results are classified from class 0 (negative) to class 6 (very high positive), indicating the severity of the allergy. Reflex testing for egg white components enhances diagnosis. This test guides treatment decisions and helps manage egg allergies effectively. Key points include:

- Detects specific IgE antibodies
- Uses FEIA method
- Results guide treatment decisions

Who Should Get Tested

The Egg White IgE test is essential for diagnosing egg allergies, which can cause symptoms from mild gastrointestinal issues to severe anaphylactic reactions. This test identifies specific IgE antibodies in the blood, confirming sensitization before immunotherapy. Key points include:

- Procedure: Uses Fluorescence Enzyme Immunoassay (FEIA) method.
- Specimen Requirements: Serum sample, 0.5 mL per 5 allergens.
- Interpretation: IgE levels range from class 0 (negative) to class 6 (very high positive).
- Reflex Testing: May include testing for ovalbumin and ovomucoid.
- Management: Guides treatment and prognosis, indicating when oral food challenges are safe.

Blood Test Preparation Guidelines

Time of day

It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.

Fasting

It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.

Stay hydrated

Drinking water prior to testing can help with sample collection.

Other factors

Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.

Medications and supplements:

Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.

Biotin supplements:

High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.

Interpreting Test Results

Understanding test results is essential for managing egg allergies effectively. The Egg White IgE test measures specific IgE antibodies to determine allergy severity. Results are classified from class 0 (negative) to class 6 (very high positive), indicating the likelihood of an allergic reaction.

- Class 0: <0.10 kU/L - Negative
- Class 1: 0.35-0.69 kU/L - Low Positive
- Class 6: >99.99 kU/L - Very High Positive

Higher scores suggest a stronger allergic response. Reflex testing for specific egg components can further refine diagnosis and guide treatment strategies.
