Specific IgE - Shrimp
- Sample Type
- Standard
- Fasting
- No
- Unit
- kUA/L
This test measures the concentration of allergen-specific Immunoglobulin E (IgE) antibodies in the blood directed against shrimp proteins (notably Pen a 1, a tropomyosin). It is a critical component of an allergy profile used to identify Type I hypersensitivities. High levels indicate sensitization, which, when combined with clinical symptoms like urticaria, angioedema, or respiratory distress, confirms a food allergy. It is essential for distinguishing between true IgE-mediated allergy and food intolerance.

Why Context Matters
Cross-reactivity is a major confounding factor; individuals allergic to dust mites or cockroaches may test positive for shrimp IgE due to similar tropomyosin proteins without having a clinical shrimp allergy. A second opinion/confirmatory oral food challenge (OFC) is often required.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
