Gluten IgG

The Goat's Milk IgE test is a specialized diagnostic tool designed to identify allergies to goat's milk by measuring Immunoglobulin E (IgE) antibodies in the blood. These antibodies are crucial indicators of allergic reactions, as they bind to allergens like goat's milk proteins, triggering symptoms such as hives, itching, and potentially severe anaphylaxis. The test's primary purpose is to confirm an allergy to goat's milk, aiding in effective management and treatment planning, including immunotherapy. A serum sample is required, typically collected in a serum gel or red-top tube, and processed using a Fluorescence Enzyme Immunoassay (FEIA) method. This involves binding IgE antibodies to allergens on an ImmunoCAP, followed by enzyme labeling and fluorescence detection. Results are categorized from negative to very strongly positive based on IgE levels, guiding clinical decisions. The test is essential for individuals experiencing allergic symptoms after consuming goat's milk products, with results available within 2-4 days.

Purpose of the test

The Goat's Milk IgE test is a diagnostic tool for identifying goat's milk allergies by measuring IgE antibodies. Key points include:

- Purpose: Diagnoses goat's milk allergy, identifies allergens, confirms sensitization for immunotherapy.
- Specimen: Requires serum sample; preferred in serum gel tube.
- Methodology: Uses Fluorescence Enzyme Immunoassay (FEIA).
- Sample preparation
- ImmunoCAP binding
- Enzyme labeling
- Incubation and washing
- Detection
- Results Interpretation: IgE levels indicate allergy likelihood.
- Clinical Relevance: Useful for symptoms like hives, itching, and anaphylaxis.
- Considerations: Not for post-immunotherapy sensitivity testing.

Who Should Get Tested

The Gluten IgG test is essential for diagnosing celiac disease, especially in those with IgA deficiency. It detects gluten-specific IgG antibodies, indicating an immune response to gluten. Key points include:

- Purpose: Diagnoses celiac disease in IgA-deficient individuals.
- Procedure: Blood sample analysis after gluten consumption.
- Antibodies: Measures IgG against gluten, tTG, and DGP.
- Sensitivity: Varies; used with other tests for accuracy.
- Results: Positive suggests gluten reaction; biopsy confirms.
- Diagnostic Cascade: Involves IgA measurement, tTG-IgA, tTG-IgG, and DGP-IgG tests.
- Monitoring: Tracks treatment effectiveness on a gluten-free diet.

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 goat's milk allergies effectively. The Goat's Milk IgE test measures specific IgE antibody levels to identify potential allergies. Here's how to interpret the results:

- Negative: <0.10 kU/L (no significant allergy detected)
- Borderline/Equivocal: 0.10-0.34 kU/L (uncertain clinical relevance)
- Equivocal: 0.35-0.69 kU/L
- Positive: 0.70-3.49 kU/L
- Strongly Positive: 3.50-17.4 kU/L
- Very Strongly Positive: ≥17.5 kU/L

Discuss results with a healthcare provider to determine appropriate management, including potential avoidance of goat's milk products and consideration of immunotherapy.
