What does the Shrimp Specific IgE test measure?

Q: What is Shrimp Specific IgE?

Shrimp reactivity is driven chiefly by tropomyosin (Pen a 1 / Pen m 1), a heat-stable muscle protein conserved across crustaceans and molluscs and homologous to invertebrate tropomyosins in house dust mite and cockroach. This homology produces frequent cross-reactivity and positive IgE in mite-sensitised patients who tolerate shellfish.

Q: Why is Shrimp Specific IgE measured?

Shrimp sIgE marks crustacean sensitisation but, because of tropomyosin cross-reactivity with inhalant allergens, a positive result in a mite-allergic patient may not reflect clinical shellfish allergy. Interpretation requires the ingestion history; the panel value alone cannot separate true food allergy from cross-sensitisation.

Shrimp Specific IgE (f24 Shrimp sIgE) is a clinical biomarker used in food-sensitivity-allergy assessment. Shrimp reactivity is driven chiefly by tropomyosin (Pen a 1 / Pen m 1), a heat-stable muscle protein conserved across crustaceans and molluscs and homologous to invertebrate tropomyosins in house dust mite and cockroach. It is measured in 1 laboratory test on BiomarkersLabs.com.

Reference Range: Class 0 (<0.35 kU/L) negative; Classes 1–6 semiquantitative.
Units: kU/L, kUA/L
