Mackerel IgE

The Mackerel IgE test is a specialized diagnostic tool designed to identify allergic reactions to mackerel, a common fish allergen. This test is vital for pinpointing the specific allergen responsible for allergic symptoms, ranging from mild reactions like hives and itching to severe cases such as anaphylaxis. Utilizing the Fluorescence Enzyme Immunoassay (FEIA) method, the test detects specific IgE antibodies in the patient's serum, indicating an allergic response. Serum samples are preferred, with stability maintained through refrigeration or freezing. Results are categorized into classes based on IgE levels, guiding healthcare providers in diagnosing and managing allergies. While the test is crucial for confirming mackerel allergies and informing treatment plans, it has limitations, such as its ineffectiveness in assessing residual sensitivity post-immunotherapy. Despite these limitations, the Mackerel IgE test remains an essential tool in allergy diagnosis, aiding in the effective management of food allergies related to fish consumption.

Purpose of the test

The Mackerel IgE test is a diagnostic tool for identifying allergies to mackerel. It helps pinpoint allergens causing symptoms like hives and anaphylaxis. Key aspects include:

- Purpose: Diagnoses mackerel allergy, confirms sensitization, and investigates allergic reactions.
- Methodology: Uses Fluorescence Enzyme Immunoassay (FEIA) to detect specific IgE antibodies.
- Specimen Requirements: Serum in gel or red-top tubes; minimum volume 0.3 mL.
- Stability: Refrigerate serum at 2-8°C for 14 days or freeze at -20°C for 90 days.
- Interpretation: IgE levels indicate allergy likelihood, categorized from negative to extremely high positive.

This test aids in allergy management, though it has limitations in certain clinical scenarios.

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 Mackerel IgE test identifies specific IgE antibodies to mackerel, indicating an allergic reaction. Results are categorized by IgE levels:

- Negative: <0.10 kU/L
- Borderline: 0.10-0.34 kU/L
- Equivocal: 0.35-0.69 kU/L
- Positive: 0.70-3.49 kU/L
- Strongly Positive: 3.50-17.49 kU/L
- Very High Positive: 17.50-49.99 kU/L
- Extremely High Positive: >50.00 kU/L

Higher IgE levels suggest a stronger allergic response, guiding treatment decisions. Understanding these results helps tailor allergy management plans effectively.
