Order Swordfish Allergy Test | Fish AllergiesA swordfish allergy test measures the amount of allergen-specific IgE antibody in the blood. IgE is the class of antibody the immune system produces when it identifies a substance, in this case a protein found in swordfish, as a threat. The result is a numerical value that helps a clinician assess sensitization to swordfish alongside a person's history and symptoms.
About Swordfish Allergy Test | Fish Allergies in Cypress
Swordfish is a large, firm-fleshed marine fish that appears in steaks, kebabs, and grilled preparations.
An allergy to swordfish falls under the broader category of fish allergy. Fish allergies are distinct from shellfish allergies, which involve crustaceans and mollusks rather than finned fish. Someone may react to one species of fish and tolerate others, or react to many, because the responsible proteins are not identical across species.
Parvalbumin is the protein most often implicated in fish allergy. It is heat-stable, meaning cooking does not reliably destroy it, and it is found in the muscle tissue of many fish. This is one reason a person can react to cooked swordfish and not only to raw fish. Symptoms can include hives, swelling, gastrointestinal upset, or, in severe cases, anaphylaxis.
Diagnosis of a swordfish allergy typically combines a detailed history with testing. A skin prick test or a specific IgE blood test such as this one can indicate sensitization. Because a positive test alone does not always mean a clinical allergy, results are interpreted by a clinician in the context of what happens when the person eats swordfish. Cross-reactivity with other fish is possible, so testing may be expanded when the history suggests it.
