FAQ
What does this test measure? Allergen-specific IgE antibodies in your blood that react to pear proteins, confirming allergy.
How accurate is the pear allergy blood test? FEIA method has 70-90% sensitivity and specificity when combined with clinical symptoms (PubMed 2020).
Can I eat pears before the test? Yes, eating pears won't affect results since the test measures antibody levels.
Will this test detect other fruit allergies? No, this test is specific to pears only - separate tests needed for other fruits.
What if my results are positive? Consult an allergist for confirmation and develop an allergy management plan including avoidance strategies.
How soon will I get my results? Results are typically available within 3-5 business days after sample collection.
More Details
What is the purpose of this test?
This test detects allergen-specific immunoglobulin E (IgE) antibodies in your blood that react to pear proteins. Using fluorescence enzyme immunoassay (FEIA) technology, it measures IgE levels to determine if pears are causing your allergic symptoms or anaphylaxis (Mayo Clinic 2025). The test helps differentiate pear allergy from other food sensitivities, supporting accurate diagnosis and targeted treatment plans.
Who would benefit from this test?
Anyone experiencing allergic symptoms after pear consumption should consider this test. It's particularly valuable for people with hives, facial swelling, breathing difficulties, or digestive issues following pear exposure. The test benefits those avoiding skin prick tests due to discomfort or medication interactions (MedlinePlus 2024). Healthcare providers also use it to confirm sensitization before starting immunotherapy treatments.
When should I order a Pear Allergy IgE Blood Test?
Order this test when clinical symptoms suggest pear allergy, especially after experiencing reactions like tingling mouth, throat swelling, or hives. It's recommended before starting allergy immunotherapy to confirm pear sensitization (AAAAI 2023). Consider testing if you have birch pollen allergy, as cross-reactivity with pear proteins is common. The test is also useful for monitoring allergy status changes over time.
How do I interpret the results?
Results are reported as IgE concentration classes from 0 to 6, indicating allergy severity levels.
IgE Level < 0.10 kU/L
- Class: 0
- Interpretation: Negative – No detectable allergy
IgE Level 0.10 – 0.34 kU/L
- Class: 1
- Interpretation: Very low – Unlikely clinical significance
IgE Level 0.35 – 0.69 kU/L
- Class: 2
- Interpretation: Low positive – Possible allergy
IgE Level 0.70 – 3.49 kU/L
- Class: 3
- Interpretation: Moderate positive – Likely allergy
IgE Level 3.50 – 17.49 kU/L
- Class: 4
- Interpretation: High positive – Very likely allergy
IgE Level 17.50 – 49.99 kU/L
- Class: 5
- Interpretation: Very high positive – Highly likely allergy
IgE Level ≥ 50.00 kU/L
- Class: 6
- Interpretation: Extremely high positive – Extremely likely allergy
Classes 2 or above (≥0.70 kU/L) suggest clinically relevant pear allergy when combined with symptom history.
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 required for this test. You don't need to fast or avoid eating pears beforehand. Continue taking your regular medications unless specifically advised otherwise by your physician. The test requires only 0.3 mL of serum collected in a gel or red-top tube (Nemours KidsHealth 2025). Stay hydrated before your appointment to ensure easier blood draw.
How often should I get tested?
Testing frequency depends on your specific clinical situation and allergy management goals.
- Initial allergy diagnosis: One-time test with symptom correlation
- Monitoring during immunotherapy: Annually or as recommended by allergist
- Symptom changes or new reactions: As needed when symptoms warrant
- Childhood allergies (potential outgrowth): Every 2–3 years in consultation with physician
Why early detection matters
Early pear allergy identification significantly improves quality of life and reduces healthcare costs. Food allergies affect approximately 8% of children and 10% of adults in the U.S., with fruit allergies causing potentially severe reactions (Mayo Clinic 2025). Prompt diagnosis decreases emergency room visits and enables proper avoidance strategies. Early detection also supports timely immunotherapy initiation when appropriate, potentially reducing long-term allergy severity.
