This panel tests for IgE antibodies to eight seafood and shellfish species. Shellfish allergy is one of the most common food allergies and can cause severe reactions including anaphylaxis. This test distinguishes between different types (shrimp, crab, lobster, clam, oyster, scallop, codfish, and salmon) to identify your specific triggers. Shellfish allergy is typically lifelong.
Allergy-specific IgE testing helps identify what your immune system is reacting to so you can avoid triggers, plan immunotherapy, and reduce symptoms.
Anyone with recurrent allergy symptoms (rash, sneezing, GI distress, breathing difficulty) who wants to identify specific triggers without elimination diets or skin testing.

A Seafood & Shellfish Allergy Test test costs $114.99 at TestWell — $120.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Ordered directly from the labs' own consumer sites, the closest equivalent lists at $132.00 at Quest Health and $139.00 at Labcorp OnDemand (list prices checked Sep 12, 2026; see the notes on how the products differ). Hospital outpatient labs typically bill around $350.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.
