Description

What is the purpose of this test?

Order a Swordfish Allergy IgE Blood Test to measure the IgE antibody levels in the blood to help detect a food allergy to swordfish. Swordfish is a highly favored fish for cooking. As swordfish are massive, the meat is generally sold as steaks. With a slightly sweet taste, swordfish is moist, mild-tasting, and flavorful. The steaks have a moderately high oil content and a firm, meaty texture. The swordfish flesh color varies from white and ivory to pink and orange in the raw form and will turn beige after cooking. For those unsure, if they like the taste of fish, its mild flavor makes it an excellent choice.

 

Swordfish is an excellent source of selenium, a micronutrient that offers valuable heart health and cancer-fighting benefits. In addition, it is rich in protein, contains vitamin B12, Omega-3, and niacin, and is low in calories and fat. Due to its many health benefits, swordfish is the main ingredient in several seafood products. Unfortunately, many individuals with food allergies or hypersensitivity may experience an adverse reaction after consuming swordfish. 

 

What other seafood or products should I avoid if I am allergic to swordfish?

Individuals should also note that there is allergic cross-reactivity between various types of fish, which means that individuals with allergies to one type of fish are likely to have or develop an allergy to other finned fish. This cross-reactivity is due to a protein found in many fish called parvalbumin. Therefore, individuals allergic to swordfish are generally advised to avoid all finned fish, including bass, cod, herring, salmon, sole, snapper, and tuna.

 

Additionally, individuals with an allergy to swordfish should also avoid the following products:

  • Imitation fish or shellfish
  • Seafood stock (fish or shrimp)
  • Fish oil, including some omega-3 supplements
  • Seafood flavorings
  • Frozen fish sticks or patties
  • Bouillabaisse
  • Salad dressing
  • Certain meat dishes that contain seafood-based ingredients
  • Surimi (minced fish paste)
  • Worcestershire sauce and anything products that contain it, such as some barbeques sauces

 

What causes an allergic reaction to swordfish?

An allergy to swordfish triggers a reaction in an individual's immune system. This is because the body views certain substances as toxic and produces IgE antibodies to these contaminants. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction.

 

When should I order a Swordfish Allergy IgE Blood Test?

Individuals may order this Swordfish Allergy IgE Blood Test if they have experienced symptoms related to a seafood allergy. Allergy symptoms vary depending on the individual, ranging from mild to severe reactions. Most food-related symptoms occur within two hours of ingestion; however, they frequently begin within minutes. In addition, the response can be delayed by four to six hours or even longer in some rare cases.

 

An allergic reaction may affect the skin, intestinal lining, and air pathways. Individuals with seafood allergies may experience one or more of the following symptoms:

 

  • Tingling sensation near or around the mouth
  • Swelling
  • Abdominal discomfort
  • Nausea or vomiting
  • Diarrhea
  • Itching or hives
  • Congestion
  • Difficulty breathing, swallowing, or wheezing
  • Lightheadedness

 

An extreme, potentially life-threatening allergic reaction known as anaphylaxis may sometimes occur. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis may include:

 

  • Rapid or increased heart rate
  • Swollen throat or lump making it difficult to breathe
  • Low blood pressure
  • Extreme dizziness or loss of consciousness
