More Details
What is the purpose of this test?
This test confirms whether you're allergic to oregano by detecting allergen-specific IgE antibodies in your blood. The Fluorescence Enzyme Immunoassay (FEIA) method specifically identifies antibodies responsible for allergic reactions to oregano (Origanum vulgare). This diagnostic tool helps distinguish oregano sensitivity from other potential allergens and supports accurate allergy diagnosis.
Who would benefit from this test?
Anyone experiencing symptoms like hives, itching, nausea, rash, coughing, or throat swelling after oregano exposure should consider this test. It's particularly valuable for people with cross-reactive herb allergies, as oregano sensitivity often occurs alongside reactions to thyme, sage, marjoram, mint, and basil. Patients considering immunotherapy also benefit from confirmation testing before treatment begins (AAAAI 2024).
When should I order an Oregano Allergy IgE test?
Order this test when you suspect oregano triggers your allergic symptoms or before starting allergen-specific immunotherapy. It's recommended for individuals with unexplained allergic reactions who consume foods containing oregano or use oregano-based products. Healthcare providers may also recommend this test as part of comprehensive allergy screening for herb and spice sensitivities.
How do I interpret the results?
IgE Level < 0.35 kU/L
- What it means: No significant sensitization
- Typical action: Oregano likely safe to consume
IgE Level 0.35–0.69 kU/L
- What it means: Low sensitization
- Typical action: Monitor symptoms, consider avoidance
IgE Level 0.70–3.49 kU/L
- What it means: Moderate sensitization
- Typical action: Avoid oregano, consult allergist
IgE Level 3.50–17.49 kU/L
- What it means: High sensitization
- Typical action: Strict avoidance, carry epinephrine
IgE Level > 17.5 kU/L
- What it means: Very high sensitization
- Typical action: Complete avoidance, emergency action plan
Results must be interpreted alongside your clinical symptoms and medical history for accurate diagnosis.

Pre-test preparation
No special preparation is required for this blood test. You don't need to fast or adjust medications. However, inform your healthcare provider if you're taking immunosuppressants or undergoing immunotherapy, as these may affect results. The blood draw takes just a few minutes and requires no dietary restrictions beforehand.
How often should I get tested?
- Initial diagnosis: One-time testing
- Monitoring immunotherapy: Every 6–12 months
- Symptom changes: As needed
- Pediatric patients: Every 2–3 years
Why early detection matters
Early identification of oregano allergies prevents potentially serious allergic reactions and reduces healthcare costs. According to the CDC, early allergy diagnosis reduces acute allergic events and emergency treatments by up to 30% (CDC Allergy Reports 2023). Identifying specific allergens enables targeted avoidance strategies and supports successful immunotherapy outcomes in over 70% of patients (Johns Hopkins Allergy Center 2024).
