Measures IgE antibodies to four shellfish allergens to help determine shellfish allergy.
This test measures the level of IgE antibodies your immune system produces in response to specific shellfish allergens (clam, crab, lobster, shrimp). Elevated IgE levels can indicate an allergic reaction. A healthcare provider will interpret the results with your medical history and symptoms to diagnose an allergy. This test helps identify potential shellfish allergens triggering reactions, aiding in allergy management and prevention.

Preparation Required

Biomarkers Tested
