Cod Fish IgE

The Cod Fish IgE test is a specialized diagnostic tool designed to detect specific IgE antibodies in the serum of individuals suspected of having an allergy to cod fish. Utilizing the Fluorescence Enzyme Immunoassay (FEIA) method, this test identifies the immune response to cod fish allergens, aiding in the diagnosis and management of allergic diseases. The test is particularly useful for confirming sensitization before initiating immunotherapy and for exploring the specificity of allergic reactions to various allergens. Serum is the preferred specimen type, with specific handling and stability requirements to ensure accurate results. The test results are classified into different classes based on IgE concentration, providing insights into the likelihood of allergic disease. While the Cod Fish IgE test is a valuable tool for allergy management, it is crucial to interpret the results within the clinical context, considering potential limitations such as false positives in cases of elevated serum IgE levels.

Purpose of the test

The Cod Fish IgE test is a diagnostic tool for detecting specific IgE antibodies in individuals suspected of having a cod fish allergy. It helps identify allergens causing allergic reactions, crucial for diagnosis and treatment. The test uses the Fluorescence Enzyme Immunoassay (FEIA) method, involving ImmunoCAPs. Serum is the preferred specimen, requiring specific handling for stability. Results are classified based on IgE levels:

- Class 0: Negative
- Class 1: Low Positive
- Class 6: Very High Positive

Interpretation must consider clinical context, as false positives can occur.

Who Should Get Tested

The Cod Fish IgE test is essential for individuals suspected of having a cod fish allergy. It identifies specific IgE antibodies, aiding in diagnosing allergic reactions. Key points include:

- Purpose: Diagnoses cod fish allergy, confirms sensitization before immunotherapy.
- Method: Uses Fluorescence Enzyme Immunoassay (FEIA) with ImmunoCAPs.
- Specimen: Requires serum, stored at 2-8°C or frozen at -20°C.
- Results: Classified from Class 0 (negative) to Class 6 (very high positive).
- Limitations: Not for post-immunotherapy sensitivity; false positives possible with high IgE levels.

This test is crucial for effective allergy management.

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 crucial for managing allergies effectively. The Cod Fish IgE test results are categorized based on IgE antibody levels:

- Class 0: <0.10 kU/L - Negative
- Class 0/1: 0.10-0.34 kU/L - Equivocal
- Class 1: 0.35-0.69 kU/L - Low Positive
- Class 2: 0.70-3.49 kU/L - Moderate Positive
- Class 3: 3.50-17.49 kU/L - High Positive
- Class 4-6: >17.50 kU/L - Very High Positive

Results should be interpreted in a clinical context, considering potential false positives and the patient's medical history.
