Quick answer
The crawfish allergy test detects immunoglobulin E antibodies against proteins from crawfish, also known as crayfish. Crawfish are freshwater crustaceans and share allergens with other shellfish such as shrimp and crab. The test is intended for people who suspect reactions after eating crawfish. A healthcare provider interprets the result with your reaction history.
What this test measures
This test measures allergen-specific immunoglobulin E against crawfish proteins. As crustaceans, crawfish contain tropomyosin, a muscle protein that is a major allergen across shrimp, crab, lobster, and related species. Reactions can include hives, swelling, oral itching, digestive symptoms, or more serious effects. The immunoassay reports a quantitative antibody level and an IgE class for crawfish.
A blood sample is collected by venipuncture at a partner laboratory and analyzed with an immunoassay. Results are reported in kilounits per liter, and total IgE and eosinophil counts may be included as supporting context. Because tropomyosin is shared among crustaceans, a crawfish result may accompany reactivity to shrimp or crab, and a broader shellfish panel can show the overall pattern. Mollusks such as clams are a separate group.
People order this test after a suspected reaction to crawfish or when they need clarity about shellfish cross-reactivity. It can support dietary planning and allergy management discussions with a clinician. Testing identifies sensitization rather than confirming a clinical allergy and does not predict reaction severity, so a qualified healthcare provider should interpret the results.
