A scallop allergy test checks your blood for antibodies that may indicate an allergic response to scallops. It is usually ordered when someone has had symptoms like hives, swelling, or breathing problems after eating scallops or other shellfish.

What it measures

  • Specific IgE to scallop — The main marker; it measures antibodies your immune system may make against scallop proteins.
  • Total IgE — A general allergy antibody level; sometimes included to help interpret the specific result.
  • Cross-reactive shellfish markers — Proteins shared with shrimp, crab, or lobster may be checked because reactions can overlap.
  • Tropomyosin — A common shellfish protein that often causes allergic reactions.

Who it is for

A primary care clinician or allergist typically orders this test after a suspected reaction to scallops. It may also be used to monitor known shellfish allergy over time.

Preparation

No fasting or special preparation is needed. Tell your clinician about any medications you take, especially antihistamines, as they may affect some allergy tests.

Results and what they mean

Results are reported as a level or class for each marker, often from negative to strongly positive. A positive result does not always mean you are allergic, and a negative result does not rule out allergy. A clinician interprets the results with your symptoms and history. This is general information, not medical advice.
