Order Swordfish Allergy Test | Fish AllergiesA swordfish allergy test measures the amount of immunoglobulin E (IgE) antibodies in the blood that react specifically to swordfish proteins. Because swordfish is a distinct species, sensitization to it does not automatically mean a person reacts to every other fish, which is why species-specific testing can be useful in evaluating a suspected fish allergy.
About Swordfish Allergy Test | Fish Allergies in Pacifica
Swordfish allergy testing uses a blood sample to look for IgE antibodies directed against swordfish.
During an allergic response, the immune system can produce IgE antibodies that recognize specific proteins in a food. A blood test detects these antibodies by exposing the sample to swordfish allergen proteins and measuring how much IgE binds to them.
Swordfish is a large, meaty fish that belongs to a different family than many common white fish. Allergic reactions to fish are often driven by a protein called parvalbumin, which is found in many species, but the amount and structure of that protein vary between fish. As a result, a person may test positive to one species and tolerate another.
Results are reported as a numerical value, often in kilounits of antibody per liter (kU/L). A higher number suggests a greater likelihood of clinical allergy, but the result must be interpreted alongside a person's history of symptoms, since a positive test alone does not confirm that eating the fish will cause a reaction.
