Order Crab Allergy Test | Shellfish AllergyCrab is a crustacean within the shellfish family, and reactions to it are driven by specific proteins that the immune system can mistakenly flag as harmful. A crab allergy test measures the amount of IgE antibodies in the blood that recognize crab proteins, offering an objective way to assess sensitization when symptoms or exposure history suggest a shellfish allergy.
About Crab Allergy Test | Shellfish Allergy in St. Charles
A blood-based IgE antibody test for crab allergy evaluates immune sensitization to crustacean proteins.
The test detects allergen-specific immunoglobulin E (IgE) antibodies that bind to proteins found in crab. When a person is sensitized, these antibodies can trigger the release of histamine and other mediators upon exposure, producing symptoms that may include hives, swelling, digestive upset, or respiratory distress.
Because shellfish allergies can be severe, identifying sensitization through a blood sample is useful when skin testing is not advisable or when a clearer picture of immune response is needed. The result is reported as a quantitative or semi-quantitative measure of crab-specific IgE, which a clinician interprets alongside symptom history and other findings.
Crab belongs to the crustacean group, which also includes shrimp, lobster, and crayfish. Many people with a crab allergy react to other crustaceans, and some may also react to mollusks such as clams or mussels. Testing helps clarify the immune response to crab specifically, while clinical guidance addresses broader dietary and safety considerations.
