About Swordfish Allergy Test | Fish Allergies in Poway
The test detects specific IgE antibodies directed against swordfish.
When the immune system mistakenly identifies a protein in swordfish as a threat, it can produce immunoglobulin E (IgE) antibodies tailored to that protein. These antibodies bind to immune cells and trigger the release of chemicals such as histamine, which cause allergy symptoms. A blood sample is analyzed for the presence and level of swordfish-specific IgE.
Swordfish is a large, firm-fleshed fish that belongs to the same broad category as tuna and mackerel. Allergic reactions to fish are most often caused by a protein called parvalbumin, which is found in many fish species. Because parvalbumin is similar across species, some people who react to one fish may also react to others, though cross-reactivity is not universal.
This screen is typically ordered alongside a clinical history. A positive result indicates sensitization to swordfish proteins, but it does not by itself prove that eating swordfish will cause symptoms. Results are interpreted together with the patient's reported reactions and any other relevant testing.
