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.

About Swordfish Allergy Test | Fish Allergies in Davis
Swordfish is a large, firm-fleshed fish that is consumed in many parts of the world. Like other fish, it contains proteins that can trigger allergic reactions in susceptible individuals.
An allergy occurs when the immune system mistakenly identifies a harmless protein as a threat and produces IgE antibodies against it. On subsequent exposure, these antibodies can prompt the release of chemicals such as histamine, leading to symptoms that may affect the skin, digestive tract, or respiratory system.
Fish allergy is distinct from shellfish allergy, and a person may react to some fish species but not others. Swordfish contains parvalbumin, a protein found in many fish and a common target of IgE antibodies. Because of this, a swordfish-specific IgE test can help clarify whether swordfish is a likely trigger for symptoms.
The test requires a blood sample, which is analyzed in a laboratory for IgE antibodies that bind to swordfish proteins. Results are typically reported as a numerical value or class, and they are interpreted alongside a person's clinical history and other findings. A positive result alone does not confirm an allergy, and a negative result does not always rule it out.
