Sample

Blood draw or sample collection at a local center

A shrimp-specific IgE blood test measures antibodies the immune system may produce against proteins in shrimp, a crustacean shellfish. It is a screening tool for suspected shellfish allergy rather than a diagnosis on its own. A clinician may order it after a reaction to shrimp or other shellfish, as part of a broader seafood panel, or when symptoms suggest sensitivity to shrimp.

• Shrimp-specific IgE Antibodies produced in response to shrimp proteins, used to assess sensitization.

• Hives, itching, or swelling after eating shrimp
• Throat tightness, wheezing, or breathing difficulty after shrimp exposure
• Stomach upset, nausea, or vomiting following shrimp meals
• Testing as part of a broader seafood or shellfish allergy panel
• A history of reactions to other crustaceans such as crab, lobster, or prawns

• No fasting is required for most IgE allergy tests
• Tell the collector about antihistamines or other medications you take
• Stay hydrated before the blood draw
• One blood sample is typically sufficient for the shrimp-specific IgE assay

An elevated shrimp-specific IgE level may indicate sensitization to shrimp proteins and can be associated with allergic reactions, some of which may be severe. A positive result alone does not confirm a clinical allergy, and a low level does not fully exclude one. Crustacean proteins can cross-react across species, so a healthcare provider should interpret results with your history.
