This test measures the concentration of allergen-specific IgE antibodies against Orange (Citrus sinensis) proteins. Within an Allergy Profile, it helps distinguish between true IgE-mediated food allergy (which carries a risk of anaphylaxis) and non-immunological food intolerance or Oral Allergy Syndrome (OAS).

Why Context Matters
Positive results may occur due to cross-reactivity with grass pollens (profilins), leading to 'false positives' where the patient has oral itching but no risk of systemic reaction. An allergist's second opinion is vital to correlate the lab value with clinical symptoms and potentially perform a skin prick test or oral food challenge.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
