Silver Birch IgE

Silver Birch IgE

The Silver Birch IgG test is a diagnostic tool designed to measure immunoglobulin G (IgG) antibodies against the silver birch tree (Betula verrucosa) in a patient's blood. It is particularly useful for individuals suspected of having an allergic reaction to birch pollen, which can cause symptoms like allergic rhinitis and asthma. The test helps determine if a patient has developed an immune response to birch pollen by measuring specific IgG antibody levels. A blood sample is required, typically collected in a red-top or gel-barrier tube, and processed to separate the serum. The test employs the Thermo Fisher ImmunoCAP method, known for its sensitivity and specificity, to detect allergen-specific IgG antibodies. Results are expressed in kU/L, indicating the immune response's severity. The test also identifies cross-reactivity with other plant allergens, aiding in comprehensive allergy management. Treatment options include allergen avoidance, medication, and allergen immunotherapy for severe cases.

Purpose of the test

The Silver Birch IgG test is a diagnostic tool designed to measure IgG antibodies against the silver birch tree in a patient's blood. This test is crucial for diagnosing birch pollen allergies and monitoring cross-reactivity with other plant allergens. Key points include:

- Purpose: Identifies immune response to birch pollen.
- Specimen: Requires 1-2 mL of blood, stable for up to 3 months frozen.
- Methodology: Uses Thermo Fisher ImmunoCAP for detection.
- Interpretation: Positive results indicate an allergic reaction.
- Clinical Significance: Guides treatment, including allergen immunotherapy.

Who Should Get Tested

The Silver Birch IgE test is essential for diagnosing allergies to silver birch. It identifies individuals with allergic responses, especially those with symptoms like respiratory issues or skin rashes after exposure to birch pollen. The test uses the ImmunoCAP FEIA method, ensuring accurate results through:

- Specimen Collection: Blood is drawn and serum separated.
- Testing Procedure: Serum is analyzed for IgE antibodies binding to birch allergens.
- Result Interpretation: IgE levels are classified from Class 0 (undetectable) to Class 6 (very severe).

This test aids in diagnosis, allergen specificity, and confirming sensitization before immunotherapy.

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 birch pollen allergies. Here's a concise guide:

- Positive Result: Indicates IgG antibodies against birch pollen, suggesting an allergic reaction.
- Antibody Levels: Higher levels may correlate with more severe symptoms.
- Cross-Reactivity: Be aware of potential reactions to foods like apples and carrots.
- Treatment Options: Consider allergen immunotherapy, antihistamines, or corticosteroids.
- Monitoring: Regular testing can help track allergy progression and treatment efficacy.

This test aids in diagnosing and managing birch pollen allergies effectively.
