Order Crab Allergy Test | Shellfish AllergyA crab allergy test measures the amount of allergen-specific IgE antibodies in the blood that react to crab proteins. Because crab belongs to the crustacean group of shellfish, reactions to crab can overlap with reactions to shrimp, lobster, and crayfish. This test uses a single blood draw and is typically used alongside a clinical history to help confirm or rule out a crab allergy.
About Crab Allergy Test | Shellfish Allergy in Normal
Crab allergy is one of the more common shellfish allergies, and it behaves differently from finned-fish allergies.
Crab allergy is caused by an immune response to proteins found in crab muscle and other tissues. The immune system produces IgE antibodies that recognize these proteins, and on subsequent exposure those antibodies trigger the release of histamine and other mediators from mast cells. Symptoms can range from itching, hives, and swelling to gastrointestinal upset, and in severe cases to breathing difficulty or anaphylaxis.
Crab is a crustacean, and the major allergenic proteins in crustaceans are tropomyosins, which are also present in shrimp, lobster, crayfish, and prawns. As a result, many people who react to crab also react to other crustaceans, and cross-reactivity with mollusks such as clams or mussels is possible but less consistent. Cooking does not reliably remove crustacean allergens, so well-cooked crab can still provoke reactions.
An IgE blood test detects sensitization to crab proteins but does not by itself prove that a clinical allergy exists. Results are interpreted together with the person's history of symptoms, the timing of reactions after eating crab, and, when appropriate, other testing. People with a known history of severe reactions should discuss any testing plan with a clinician before proceeding.
