Peanut (Specific IgE)
- Sample Type
- Standard
- Fasting
- No
- Unit
- kUA/L
This test measures the concentration of Specific Immunoglobulin E (sIgE) antibodies to peanut allergens in the blood. Within an Allergy Profile, it helps diagnose Type I hypersensitivity. Peanut allergies are among the most common and severe food allergies, often associated with a risk of life-threatening anaphylaxis.

Why Context Matters
High IgE levels indicate 'sensitization' but do not always correlate with a clinical reaction (false positives). Cross-reactivity with other legumes or pollens (like birch) can occur. A second opinion may involve a Component Resolved Diagnostics (CRD) test for Ara h 2, which is more specific for true anaphylactic risk.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
