Specific IgE - Soy
- Sample Type
- Standard
- Fasting
- No
- Unit
- kUA/L
This component measures IgE antibodies against soy (Glycine max) proteins. Within a comprehensive Allergy Profile, soy is a major allergen, especially in pediatric populations and those on vegetarian diets. Soy contains several allergenic proteins (like Gly m 4, 5, and 6). High levels help identify soy as a trigger for gastrointestinal distress, atopic dermatitis, or anaphylaxis. It is particularly important for patients with birch pollen allergies, as they may experience cross-reactivity with soy (oral allergy syndrome).

Why Context Matters
Soy allergy testing is notoriously complex due to high cross-reactivity with other legumes (peas, peanuts, lentils). A patient may test positive for Soy IgE because they are allergic to peanuts, without actually reacting to soy. Component-resolved diagnostics (CRD) may be needed as a second step to identify the specific soy protein involved.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
