Sardine IgE

The Sardine IgG test is a diagnostic tool designed to evaluate the immune response to sardine proteins by measuring IgG antibody levels in the serum. IgG antibodies are crucial for long-term immunity, and their presence can indicate an immunological response to sardines. This test is primarily used for food sensitivity testing, helping identify individuals who may experience symptoms like gastrointestinal issues, skin rashes, or respiratory problems after consuming sardines. While it provides insights into potential allergic reactions, it is important to note that IgG antibodies alone do not confirm a food allergy. Comprehensive allergy diagnosis typically requires assessing both IgG and IgE antibodies. The test involves collecting a blood sample, which is then analyzed using Enzyme Immunoassay (EIA) technology. Results are interpreted in the clinical context, considering the patient's symptoms and medical history. Despite its utility, the test has limitations, such as potential false positives, and should be used alongside other diagnostic methods.

Purpose of the test

The Sardine IgG test evaluates the immune response to sardine proteins by measuring IgG antibodies in the serum. Its objectives include:

- Food Sensitivity Testing: Identifies potential sensitivities or intolerances to sardine, aiding those with symptoms like gastrointestinal issues or skin rashes.

- Allergy Diagnosis: Offers insights into allergic reactions, though IgG alone doesn't confirm allergies; IgE assessment is also needed.

- Dietary Management: Guides dietary changes by identifying foods that trigger immune responses, helping manage symptoms effectively.

The test involves blood collection, serum separation, and analysis using Enzyme Immunoassay technology. Results are interpreted in clinical context, considering limitations like specificity and potential false positives.

Who Should Get Tested

Individuals who suspect they have a sardine or pilchard allergy should consider the Sardine IgE test. This test is essential for:

- Diagnosis: Confirming the presence of specific IgE antibodies to sardine proteins.
- Symptom Investigation: Identifying the allergen causing symptoms like hives, itching, or anaphylaxis.
- Pre-Immunotherapy: Assessing sensitization before starting desensitization treatments.

While the test is reliable, it’s crucial to interpret results in a clinical context due to potential false positives. The test is cost-effective, with results typically available in 3-4 days.

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 effective health management. The Sardine IgG test evaluates the immune response to sardine proteins by measuring IgG antibodies. Here's a brief guide to interpreting the results:

- Positive Results: Indicates an immune response to sardine, suggesting potential sensitivity.
- Negative Results: No significant immune response detected.
- Clinical Context: Consider symptoms and medical history for accurate interpretation.

Remember, IgG levels alone don't confirm allergies. Consult healthcare providers for comprehensive analysis and dietary advice.
