Sample

Blood draw or sample collection at a local center

A scallop-specific IgE blood test detects antibodies the immune system may produce against proteins in scallops. It is a screening tool for suspected shellfish allergy, not a diagnosis by itself. A clinician may order it after a reaction to scallops or other shellfish, as part of a broader seafood panel, or when symptoms suggest sensitivity to scallops and related mollusks.

• Scallop-specific IgE Antibodies produced in response to scallop proteins, used to assess sensitization.

• Hives, itching, or swelling after eating scallops or shellfish
• Stomach upset, nausea, or vomiting following shellfish meals
• Throat tightness or breathing difficulty after shellfish exposure
• Testing as part of a broader seafood or shellfish allergy panel
• A history of reactions to other mollusks such as clams or oysters

• No fasting is required for most IgE allergy tests
• Mention antihistamines or other medications to the collector
• Stay hydrated before the blood draw
• One blood sample is typically enough for the scallop-specific IgE assay

An elevated scallop-specific IgE level may indicate sensitization to scallop proteins and can be associated with allergic reactions, but a positive result alone does not prove a clinical allergy. A low or undetectable level lowers the likelihood of allergy without excluding it. Cross-reactivity between shellfish species is possible, so a healthcare provider should interpret the result with your history.
