Specific IgE - Peanut
- Sample Type
- Standard
- Fasting
- No
- Unit
- kUA/L
Measures IgE antibodies specific to peanut allergens (e.g., Ara h 1, 2, 3). Peanut allergy is one of the most common food allergies and is frequently associated with severe systemic reactions (anaphylaxis). Within a vegetable allergy profile, this helps quantify the level of sensitization, which often correlates with the likelihood of a clinical reaction.

Why Context Matters
IgE levels do not always predict the severity of a reaction. Cross-reactivity with other legumes (soy, peas) can lead to 'false positive' sensitization without clinical symptoms. Component-resolved diagnostics (e.g., testing specifically for Ara h 2) may be needed to assess the risk of severe reactions versus oral allergy syndrome.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
