Order Swordfish Allergy Test | Fish AllergiesA swordfish allergy screen measures the amount of immunoglobulin E (IgE) antibodies in the blood that react to swordfish proteins.

About Swordfish Allergy Test | Fish Allergies in Belleville
Swordfish is a large, firm-fleshed marine fish that appears in grilled, seared, and raw preparations. Although fish allergy is less common than shellfish allergy, it can be serious, and reactions may occur to one species while others are tolerated.
The test uses a blood sample to quantify IgE antibodies that bind specifically to swordfish allergens. Because IgE responses are antibody-based, the result reflects immune sensitization rather than a direct measure of clinical symptoms.
Fish allergy symptoms can include hives, itching, swelling of the lips or face, stomach upset, wheezing, or difficulty breathing, typically appearing within minutes to a couple of hours after eating. A blood test is one part of the evaluation; a clinician interprets the number alongside the person's history and may recommend further testing.
Some people with fish allergy react to a protein called parvalbumin, which is found in many fish species, while others respond to different proteins. Sensitivity to swordfish does not automatically mean every other fish will cause a reaction, and the pattern varies from person to person.
