FAQ
What does this test measure? IgE antibodies specific to mango allergens in your blood to confirm or rule out mango allergy.
How accurate are the results? The FEIA method used has >85% sensitivity and specificity, making it highly reliable for allergy diagnosis (Mayo Clinic 2024).
Can I eat mango before the test? Yes, maintain your normal diet. Avoiding mango won't affect the accuracy of IgE antibody detection.
What if I'm taking allergy medications? Continue current medications as prescribed. Unlike skin tests, blood tests aren't affected by antihistamines.
Do I need to fast for this test? No fasting is required. Stay hydrated and eat normally before your blood draw.
How soon will I get my results? Results are typically available within 2-5 business days through your secure online portal.
More Details
What is the purpose of this test?
This test measures immunoglobulin E (IgE) antibodies specific to mango allergens in your blood. When your immune system overreacts to mango proteins found in the peel and flesh, it produces these antibodies. The test uses Fluorescence Enzyme Immunoassay (FEIA) technology to detect and quantify these antibodies, helping confirm whether your symptoms are truly due to mango allergy (Mayo Clinic 2024).
Who would benefit from this test?
This test is ideal for anyone who suspects they have a mango allergy based on symptoms like oral irritation, skin reactions, digestive issues, or respiratory problems after mango exposure. It's particularly valuable for people with pollen-food syndrome, those allergic to related plants in the Anacardiaceae family (like cashews), or individuals seeking to avoid unnecessary dietary restrictions (Journal of Allergy and Clinical Immunology 2023).
When should I order this test?
Order this test if you've experienced allergic reactions within minutes to hours of eating mango or touching mango peel. Common symptoms include tingling around the mouth, hives, swelling, nausea, congestion, or difficulty breathing. The test is also recommended for preventive screening if you have known cross-reactive allergies or before considering immunotherapy (CDC 2023).
How do I interpret the results?
IgE < 0.35 kU/L
- What it means: No sensitization detected
- Typical action: Mango allergy unlikely
IgE 0.35–0.69 kU/L
- What it means: Borderline sensitization
- Typical action: Monitor symptoms, consider retesting
IgE 0.70–3.49 kU/L
- What it means: Moderate sensitization
- Typical action: Likely allergic, avoid mango
IgE 3.50–17.49 kU/L
- What it means: High sensitization
- Typical action: Definite allergy, strict avoidance
IgE > 17.50 kU/L
- What it means: Very high sensitization
- Typical action: Severe allergy risk, carry epinephrine
Results must be interpreted alongside your clinical symptoms - even low levels don't completely exclude allergy risk.
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 preparation is needed for this test. Continue eating normally and stay hydrated before your blood draw. Don't stop taking prescribed allergy medications without consulting your healthcare provider, as they won't interfere with the blood test results (NIAID 2021).
How often should I get tested?
- Initial diagnosis: One-time testing
- Monitoring treatment response: Every 1–2 years
- Before immunotherapy: As recommended by allergist
- Symptom changes: Retest when symptoms worsen or improve
- Childhood allergies: Retest every 2–3 years (may outgrow)
Why early detection matters
Early identification of mango allergy prevents potentially life-threatening anaphylactic reactions and reduces healthcare costs associated with emergency care. Mango allergy prevalence is increasing due to global consumption, and cross-reactivity with cashews and other related plants affects 20-40% of sensitized individuals (World Allergy Organization 2022). Knowing your allergy status allows you to make informed dietary choices and carry emergency medications when needed.
