About Crab Allergy Test | Shellfish Allergy in Carson
Crab is a crustacean and one of the more common shellfish allergens.
Shellfish allergies are divided into two broad groups: crustaceans, which include crab, shrimp, lobster, and crayfish, and mollusks, which include clams, mussels, and scallops. Crab falls into the crustacean group, and its major allergen is a muscle protein called tropomyosin.
Reactions to crab can appear within minutes to a couple of hours after eating or, in some cases, after handling or inhaling cooking vapors. Symptoms may include hives, swelling, stomach upset, wheezing, or in severe cases anaphylaxis. A blood test detects crab-specific IgE antibodies and is often used when skin testing is not practical.
A positive result indicates sensitization to crab proteins, but it does not by itself confirm that a clinical allergy will occur. Results are interpreted alongside a person's history and other findings, and avoidance of crab and related crustaceans is typically advised when an allergy is confirmed.
