What is the purpose of this test?
Order this Codfish Allergy IgE Blood Test to measure the IgE antibody levels in the blood to help detect a food allergy to codfish. Seafood allergies affect about 1-3% of Americans, with shellfish allergies being the most common and severe. Codfish belongs to the Gadidae family, native to the northwest Atlantic Ocean and found in Canadian waters, Greenland, and North Carolina. Codfish is a cold-water fish that can survive nearly freezing to 68 degrees Fahrenheit and is located in fresh and marine water, making it a cost-effective fish distributed globally. Due to its cost-effectiveness and versatility, codfish is the main ingredient in several fish and seafood products. Unfortunately, many individuals with food allergies or hypersensitivity may experience an adverse reaction after consuming codfish. Individuals should also note that a codfish allergy may indicate allergies to other seafood, such as mackerel, herring, salmon, and pollack.
What other food products should I avoid if I have a codfish allergy?
Individuals allergic to codfish should not only avoid the specific seafood that causes the reaction but also avoid other seafood-based products, including:
- 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
Additionally, individuals may be allergic to fish and shellfish to the point that avoiding seafood markets, handling seafood, or being around cooking seafood is necessary.
What causes an allergic reaction to codfish?
The major allergen in codfish is the muscle protein parvalbumin, a calcium-binding protein. Once an individual with a codfish allergy ingests or comes in direct skin contact with codfish, it triggers a response in an individual's immune system. The immune system views specific proteins or substances as harmful and produces IgE antibodies to combat these invaders. Unfortunately, these antibodies cause the chemical histamine to be released, which will cause the symptoms associated with an allergic reaction.
When should I order a Codfish Allergy IgE Blood Test?
Individuals may order this Codfish 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
