Kiwi IgE

The Kiwi IgE serum test is a vital diagnostic tool used to identify allergies to kiwi fruit by detecting specific IgE antibodies in a patient's serum. This test is essential for individuals who experience allergic reactions such as hives, itching, swelling, nausea, and respiratory issues after consuming kiwi. A blood sample is collected, processed, and analyzed using Fluorescence Enzyme Immunoassay (FEIA) to determine the presence and level of IgE antibodies. Results are classified into different classes, indicating the likelihood of an allergic response. A positive result suggests an increased risk of allergic disease, although diagnosis should also consider patient history and clinical symptoms. The test is performed on weekdays, with results typically available within a few days. Understanding the test's methodology and clinical implications is crucial for managing kiwi allergies, which can be severe and potentially life-threatening, especially in individuals with other allergies or sensitivities.

Purpose of the test

The Kiwi IgE serum test is essential for diagnosing kiwi fruit allergies. It identifies specific IgE antibodies, indicating an immune response to kiwi allergens. Key points include:

- Purpose: Diagnose and manage kiwi allergies.
- Symptoms: Hives, itching, swelling, nausea, wheezing.
- Specimen Collection: Blood sample, serum gel or red-top tube.
- Stability: Refrigerated for 14 days, frozen for 90 days.
- Methodology: Fluorescence Enzyme Immunoassay (FEIA).
- Interpretation: Class 0-6, indicating negative to strongly positive results.
- Clinical Considerations: Severe reactions possible, linked to latex allergies.

Who Should Get Tested

The Kiwi IgE serum test is essential for diagnosing kiwi fruit allergies. It is particularly useful for individuals experiencing symptoms like:

- Hives
- Itching
- Swelling of the mouth, tongue, and lips
- Nausea and vomiting
- Diarrhea
- Wheezing and airway constriction

A blood sample is collected, and specific IgE antibodies are detected using Fluorescence Enzyme Immunoassay. Results are classified into classes indicating the likelihood of an allergy. A positive result suggests an increased risk of allergic disease, but diagnosis should also consider patient history and clinical findings.

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 kiwi allergies. The Kiwi IgE serum test helps identify specific IgE antibodies, indicating an immune response to kiwi allergens. Here's how to interpret the results:

- Class 0: <0.10 kU/L, negative.
- Class 1: 0.10-0.34 kU/L, borderline.
- Class 2: 0.35-3.49 kU/L, equivocal.
- Class 3: 3.50-17.4 kU/L, positive.
- Class 4-6: >17.5 kU/L, strongly positive.

A positive result suggests a higher likelihood of allergy, but diagnosis should also consider clinical history and symptoms.
