Orange IgG

The Orchard Grass IgE test is a vital diagnostic tool used to identify allergies to orchard grass by measuring specific IgE antibodies in the blood. These antibodies are crucial indicators of the body's immune response to allergens, and their presence confirms sensitization to orchard grass. The test is essential for diagnosing allergies, which can manifest as symptoms like sneezing, nasal congestion, itchy eyes, and, in severe cases, anaphylaxis. Conducted through a blood sample, the test employs a Fluorescence Enzyme Immunoassay (FEIA) method, where the serum is analyzed for IgE levels. Results are reported in kU/L, with classifications ranging from negative to extremely high positive, guiding the diagnosis and management of allergies. The test aids in defining specific allergens, confirming sensitization before immunotherapy, and ensuring targeted treatment. With a quick turnaround time and high specificity, the Orchard Grass IgE test is a reliable method for allergy diagnosis and management.

Purpose of the test

The Orchard Grass IgE test is essential for diagnosing allergies to orchard grass by detecting specific IgE antibodies in the blood. This test confirms sensitization and identifies allergens responsible for symptoms like sneezing and itchy eyes. Key aspects include:

- Purpose: Identifies specific IgE antibodies, confirming allergy presence.
- Procedure: Blood sample analyzed using Fluorescence Enzyme Immunoassay.
- Clinical Utility: Diagnoses allergies, defines allergens, confirms sensitization.
- Specimen Requirements: 0.3 mL serum, stored refrigerated or frozen.
- Interpretation: IgE levels indicate allergy severity, guiding treatment plans.

Who Should Get Tested

The Orange IgG test is crucial for diagnosing and managing food allergies related to oranges. It measures IgG antibodies, which can indicate sensitization to allergens. This test is particularly useful for individuals with chronic symptoms like gastrointestinal issues or skin rashes after consuming oranges.

Key Points:

- Procedure: Blood sample collection, serum separation, and enzyme immunoassay (EIA) method.
- Results Interpretation:
- Negative: IgG levels below 2.0 mcg/mL.
- Positive: Levels above 0.70 mcg/mL.
- Clinical Utility: Useful in conjunction with other tests.
- Limitations: Not FDA-approved; interpret with caution.

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 orchard grass allergies. The Orchard Grass IgE test measures specific IgE antibodies in the blood, indicating sensitization to the allergen. Here's how to interpret the results:

- Negative: IgE < 0.10 kU/L
- Equivocal/Borderline: IgE 0.10-0.34 kU/L
- Low Positive: IgE 0.35-0.69 kU/L
- Moderate Positive: IgE 0.70-3.49 kU/L
- High Positive: IgE 3.50-17.49 kU/L
- Very High Positive: IgE 17.50-99.99 kU/L
- Extremely High Positive: IgE > 99.99 kU/L

Values below 100 kU/L suggest an allergy, guiding treatment plans.
