Crayfish (rf320) IgE details
What Crayfish (rf320) IgE shows
Crayfish, also called crawfish, is a freshwater crustacean related to lobster, shrimp and crab. This test measures IgE antibodies to crayfish proteins to check whether your immune system is sensitized to them. A positive result can help explain allergic symptoms such as hives, swelling, vomiting or breathing problems after eating crayfish. Crustaceans share similar proteins, especially tropomyosin, which is also found in dust mites and cockroaches, so a positive result can reflect cross-reactivity rather than a crayfish-specific allergy. IgE shows sensitization, not necessarily allergy, so the result needs to be read against your symptoms and history.
