FAQ
What does this test measure? IgE antibodies specific to kiwi fruit allergens using sensitive laboratory methods.
How accurate is the kiwi allergy test? Serum-specific IgE tests have 70-90% accuracy for detecting food allergies (PubMed Central 2020).
Can I eat kiwi before the test? Yes, recent kiwi consumption won't affect your IgE antibody levels.
Will this detect all kiwi reactions? No, it only detects IgE-mediated allergies, not food intolerances or delayed reactions.
What if I'm taking allergy medications? Inform the lab about current medications, especially immunotherapy or anti-allergy drugs.
How soon can symptoms appear after eating kiwi? Most reactions occur within minutes to 2 hours, though some may be delayed.
More Details
What is the purpose of this test?
The Kiwi Allergy IgE Blood Test measures immunoglobulin E (IgE) antibodies specific to kiwi fruit allergens in your blood. Using Fluorescence Enzyme Immunoassay (FEIA) methodology, this test detects your immune system's allergic response to kiwi proteins (Mayo Clinic Labs 2025). It helps establish whether you have an IgE-mediated allergy to kiwi fruit, which can cause symptoms ranging from mild oral reactions to severe anaphylaxis.
Who would benefit from this test?
This test is valuable for people experiencing allergic symptoms after eating kiwi, including mouth tingling, swelling, hives, or difficulty breathing. It's also useful for individuals with suspected food allergies who need diagnostic confirmation, those with family history of fruit allergies, and people experiencing unexplained allergic reactions (Testing.com 2021).
When should I order a Kiwi Allergy IgE Blood Test?
Order this test if you experience allergic symptoms shortly after kiwi ingestion or need to rule out kiwi allergy in your food allergy evaluation. Symptoms may include tingling around the mouth, swelling, abdominal discomfort, nausea, vomiting, diarrhea, itching, hives, congestion, difficulty breathing, or lightheadedness. In severe cases, anaphylaxis may occur, requiring immediate medical attention.
How do I interpret the results?
IgE < 0.35 kU/L (Class 0)
- What it means: No sensitization detected
- Typical action: Allergy unlikely
IgE 0.35–0.69 kU/L (Class 1)
- What it means: Low positive/borderline
- Typical action: Monitor symptoms, consider retesting
IgE 0.70–3.49 kU/L (Class 2)
- What it means: Moderate positive
- Typical action: Avoid allergen as needed
IgE 3.50–17.49 kU/L (Class 3)
- What it means: High positive
- Typical action: Strict avoidance recommended
IgE 17.50–49.99 kU/L (Class 4)
- What it means: Very high positive
- Typical action: Carry emergency medication, strict avoidance
IgE 50.00–99.99 kU/L (Class 5)
- What it means: Very high positive
- Typical action: Complete avoidance, consult specialist
IgE ≥ 100 kU/L (Class 6)
- What it means: Extremely high positive
- Typical action: Strict avoidance, comprehensive allergy management
IgE levels ≥0.70 kU/L (class 2 or above) suggest positive sensitization to kiwi, with higher classes indicating stronger reactions.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
Pre-test preparation
No special fasting is required for this test. Simply inform the lab about any current medications, especially immunotherapy treatments or anti-allergy drugs, as these may affect results. The test requires a standard blood draw via venipuncture.
How often should I get tested?
- Initial diagnosis – Once for confirmation
- Monitoring treatment response – Every 1–2 years
- Before immunotherapy – As directed by allergist
- Symptom changes – When symptoms worsen or improve
Why early detection matters
Early detection of kiwi allergies through IgE testing can prevent severe reactions like anaphylaxis, reducing emergency healthcare costs and improving quality of life (Mayo Clinic Labs 2025). Food allergies affect approximately 8% of children and 10.8% of adults in the US, making timely diagnosis crucial for proper management.
