Mango IgE

The Mango IgG test is a diagnostic tool designed to detect immunoglobulin G (IgG) antibodies specific to mango allergens in a patient's serum. It plays a crucial role in assessing immune responses to mango, aiding in the diagnosis and management of allergic reactions. The test is particularly useful for individuals experiencing symptoms like hives, itching, swelling, stomach cramps, diarrhea, or anaphylaxis after consuming mango. The procedure involves collecting a serum sample, which is analyzed using an enzyme immunoassay (EIA) to measure IgG antibody concentrations. Results are interpreted based on antibody levels, with specific ranges indicating negative, positive, or borderline immune responses. While the test is valuable for diagnosing mango allergies, guiding dietary elimination, and confirming sensitization before immunotherapy, it has limitations. A positive result indicates sensitization but not necessarily an allergy. Therefore, results should be interpreted alongside clinical symptoms and other diagnostic methods for accurate allergy management.

Purpose of the test

The Mango IgG test is a diagnostic tool designed to detect IgG antibodies specific to mango allergens in a patient's serum. Its primary purpose is to identify individuals with an immune response to mango, aiding in the diagnosis and management of allergic reactions. The procedure involves:

- Sample Preparation: Serum is separated via centrifugation.
- Antigen Binding: Serum is exposed to mango allergens.
- Enzyme Labeling: An enzyme-labeled antibody binds to IgG.
- Colorimetric Detection: A color change indicates IgG presence.
- Quantification: Spectrophotometry measures IgG concentration.

Results guide allergy diagnosis, dietary management, and immunotherapy planning.

Who Should Get Tested

The Mango IgE test is essential for diagnosing mango allergies, helping to identify specific allergens responsible for allergic reactions. This test is crucial for:

- Diagnosing allergies by detecting specific IgE antibodies.
- Defining allergens to tailor treatment plans.
- Confirming sensitization before immunotherapy.

Using the Fluorescence Enzyme Immunoassay (FEIA) method, the test ensures high sensitivity and specificity. Proper specimen handling is vital:

- Store samples at 4°C or freeze for up to 90 days.
- Use a serum gel or red-top tube for collection.

Results are available within 1-2 business days, aiding timely patient care.

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 effective allergy management. The Mango IgG test identifies immunologic sensitization to mango allergens, aiding in allergy diagnosis. Here's how to interpret the results:

- Negative: Less than 2.0 mcg/mL, indicating no significant immune response.
- Positive: 2.0 to 200 mcg/mL, suggesting sensitization but not confirming an allergy.
- Borderline/Equivocal: 2.0 to 4.0 mcg/mL, requiring further evaluation.

Remember, results should be considered alongside clinical symptoms and other diagnostic methods for accurate allergy management.
