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 provides objective antibody data that can help clarify whether crab is a trigger for symptoms.
About Crab Allergy Test | Shellfish Allergy in Fallbrook
Crab allergy is one of the more common shellfish allergies and can range from mild oral itching to severe systemic reactions.
Shellfish allergy involves an immune response to proteins found in crustaceans and mollusks. Crab, along with shrimp, lobster, and crayfish, belongs to the crustacean category, and the major allergenic protein in these species is tropomyosin. Because tropomyosin is structurally similar across crustaceans, a sensitivity to crab often coincides with sensitivity to other shellfish.
Symptoms of a crab allergy may include hives, swelling, stomach upset, wheezing, or in serious cases, anaphylaxis. Reactions can occur within minutes of eating crab or, in some people, after handling or inhaling steam from cooking shellfish. A blood test measuring crab-specific IgE antibodies can support a diagnosis when skin testing is not practical or when a history of severe reactions makes direct exposure risky.
IgE antibody results are reported as a numerical value and are interpreted alongside a person's symptom history. A positive result indicates sensitization to crab proteins, which does not by itself confirm a clinical allergy. A negative result generally makes crab allergy less likely, though it does not rule out all forms of shellfish-related reactions. Testing is most useful when ordered and reviewed by a qualified healthcare professional.
