Onion IgG

The Orange IgE test is a vital diagnostic tool used to identify specific IgE antibodies in the blood, indicating an immune response to orange allergens. This test is essential for diagnosing orange allergies, which can cause symptoms like skin rashes, respiratory issues, and even anaphylaxis. Utilizing Fluorescence Enzyme Immunoassay (FEIA), the test offers high accuracy by minimizing non-specific binding. It requires a serum specimen, preferably collected in a serum gel tube, with a minimum volume of 0.3 mL. Specimens remain stable for up to 14 days when refrigerated or 90 days if frozen. Results are typically available within 1 to 3 business days. The test categorizes IgE levels into classes, helping healthcare providers assess the likelihood of an allergic reaction. Clinically, it aids in diagnosing allergies, defining allergens, confirming sensitization before immunotherapy, and investigating allergic reactions, making it indispensable for effective allergy management.

Purpose of the test

The Orange IgE test is a vital diagnostic tool for identifying allergies to oranges by detecting specific IgE antibodies. Its primary purpose is to aid healthcare providers in diagnosing and managing orange allergies, which can cause symptoms ranging from skin rashes to anaphylaxis. Key aspects include:

- Methodology: Utilizes Fluorescence Enzyme Immunoassay (FEIA) for accurate results.
- Specimen Requirements: Requires a serum specimen, with a minimum volume of 0.3 mL.
- Turnaround Time: Results are typically available within 1 to 3 business days.
- Interpretation: Results are categorized into classes indicating the likelihood of an allergic reaction.

This test is crucial for confirming sensitization and guiding treatment plans.

Who Should Get Tested

The Onion IgG test is a specialized tool for identifying potential sensitivities to onion allergens. It measures IgG antibodies in the serum using an Enzyme Immunoassay (EIA). Key points include:

- Specimen Collection: Blood is collected in a red-top or serum gel tube, requiring 0.5 mL of serum.
- Storage: Serum can be stored at ambient temperature for 7 days, refrigerated for 28 days, or frozen for 365 days.
- Interpretation: Results indicate immunologic sensitization, not a definitive allergy.
- Clinical Use: Useful in specific cases, not FDA-approved for diagnostics.

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 Orange IgE test identifies specific IgE antibodies to orange allergens, aiding in diagnosis and treatment planning. Here's a quick guide to interpreting results:

- Class 0: <0.10 kU/L, negative.
- Class 0/1: 0.10-0.34 kU/L, equivocal.
- Class 1: 0.35-0.69 kU/L, low positive.
- Class 2: 0.70-3.49 kU/L, moderate positive.
- Class 3: 3.50-17.49 kU/L, high positive.
- Class 4-5: 17.50-99.99 kU/L, very high positive.
- Class 6: >99.99 kU/L, extremely high positive.

Results guide healthcare providers in confirming sensitization and planning immunotherapy.
