Because crawfish is a crustacean, reactions to it often overlap with allergies to other shellfish such as shrimp, crab, and lobster.
About Crawfish Allergy Test | Shellfish Allergy in Roseville
Crawfish allergy is an immune response to proteins found in the muscle and cooking fluids of the crustacean.
When a person with a crawfish allergy eats or handles crawfish, the immune system treats certain proteins as harmful and produces immunoglobulin E antibodies against them. On later exposure, those antibodies trigger the release of histamine and other chemicals, which cause symptoms that can include hives, swelling, stomach upset, wheezing, or, in severe cases, anaphylaxis.
The blood test detects crawfish-specific IgE in a sample drawn by a trained phlebotomist. Results are reported as a numerical value or class, and a higher value generally indicates a greater likelihood of clinical allergy, though the test alone cannot predict how severe a future reaction will be.
Crawfish belong to the crustacean group of shellfish, alongside shrimp, crab, and lobster. People allergic to one crustacean are frequently advised to avoid others, and some also react to mollusks such as clams or mussels. A clinician interprets the test alongside the person's history and may recommend additional testing or an oral food challenge.
