Lemon IgG

The Lentil IgE test is a specialized diagnostic tool used to detect IgE antibodies in a patient's serum, specifically targeting lentil allergens. This test is essential for diagnosing lentil allergies, which can cause symptoms like skin rashes, respiratory issues, and gastrointestinal problems. By identifying the specific allergen responsible for these reactions, the test aids in confirming sensitization and guides treatment decisions, including immunotherapy.

A blood sample is collected in a red top or serum gel tube, with a minimum volume of 0.3 mL required for testing. The sample is centrifuged to separate the serum, which is then analyzed using the Fluorescence Enzyme Immunoassay (FEIA) method. Results are categorized into classes indicating the level of allergic sensitivity, from negative to extremely high.

The test results must be interpreted in conjunction with the patient's clinical history and symptoms, as false positives can occur. Typically performed Monday through Friday, the Lentil IgE test provides timely results, aiding in the effective management of lentil allergies.

Purpose of the test

The Lentil IgE test is a diagnostic tool for identifying allergies to lentils by measuring IgE antibodies in serum. Its objectives include:

- Diagnosing lentil allergies by detecting specific IgE antibodies.
- Identifying allergens causing allergic reactions or anaphylaxis.
- Confirming sensitization before immunotherapy.
- Investigating allergic reactions to other substances.

The test uses a blood sample, processed to serum, and employs Fluorescence Enzyme Immunoassay (FEIA) for analysis. Results guide treatment strategies, considering clinical context and patient history. This test is crucial for managing lentil allergies, especially in pediatric cases.

Who Should Get Tested

The Lemon IgG test is primarily for patients with food-related complaints. It helps identify immunologic sensitization to lemon but doesn't confirm a food allergy. Key considerations include:

- Dietary Elimination and Challenge: Useful for evaluating lemon's role in symptoms.
- Immunotherapy Preparation: Confirms sensitization before treatment.
- Allergic Reaction Investigation: Identifies potential allergens.

The test involves a blood sample, with results in 3 days. It's crucial to interpret results alongside other diagnostic methods, as IgG presence alone doesn't confirm an allergy.

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 lentil allergies effectively. The Lentil IgE test measures IgE antibodies in the serum, indicating allergic sensitivity levels. Results are categorized as follows:

- Negative (< 0.1 kU/L): No significant sensitivity.
- Equivocal/Low (0.10 - 0.31 kU/L): Possible reaction.
- Low (0.32 - 0.55 kU/L): Low sensitivity.
- Moderate (0.56 - 1.40 kU/L): Moderate sensitivity.
- High (1.41 - 3.90 kU/L): High sensitivity.
- Very High (3.91 - 19.00 kU/L): Very high sensitivity.
- Extremely High (> 19.00 kU/L): Extremely high sensitivity.

Consider clinical context and patient history for accurate interpretation.
