Order Crab Allergy Test | Shellfish AllergyA crab allergy test measures the amount of specific IgE antibodies in the blood that react to crab proteins. Because crab belongs to the shellfish group, this test is often ordered alongside other shellfish panels to clarify which species trigger a response. The result helps distinguish a true immune-mediated allergy from other reactions to shellfish, such as intolerance or food poisoning.
About Crab Allergy Test | Shellfish Allergy in Merced
Shellfish allergy is one of the most common food allergies in adults, and crab is a frequent trigger within the crustacean family.
Crab allergy occurs when the immune system identifies proteins in crab, such as tropomyosin, as harmful and produces IgE antibodies against them. On subsequent exposure, these antibodies prompt the release of histamine and other chemicals, leading to symptoms that may include hives, swelling, stomach upset, or breathing difficulty.
Because crustaceans share similar proteins, a person allergic to crab may also react to shrimp, lobster, and crayfish. Mollusks such as clams, oysters, and mussels are biologically distinct, so reactivity to one group does not always mean reactivity to the other. A blood test for crab-specific IgE can help map that pattern when interpreted with a clinical history.
Testing is typically used when a person reports symptoms after eating crab or when a clinician needs to evaluate a suspected shellfish allergy. Results are reported as a quantitative antibody level, and the significance of any value depends on the individual's exposure history and symptoms. A negative result does not entirely rule out allergy, and a positive result does not by itself confirm that a reaction will occur.
