What is the purpose of this test?
Order a Red Snapper Allergy IgE Blood Test to measure the IgE antibody levels in the blood to help detect a food allergy to red snapper. One of the most popular of all white fish is the red snapper. It is renowned for its slightly sweet, nutty taste and firm, flaky, and slightly pink meat. Red snapper is usually baked or grilled whole but may also be filleted and pan-fried, poached, barbecued, or added to mixed fish dishes such as stews, curries, or salads. Because individuals react to both cooked and raw fish, it is presumed that the allergens are heat-resistant.
Red snapper is a high-protein, low-calorie fish which contains all nine essential amino acids. It is also filled with vitamins D and E, a good source of omega-3 fatty acids, and contains the minerals magnesium and selenium. However, it does have relatively high mercury levels, which may pose a health risk. Nevertheless, red snapper is very healthy as long as it is eaten in moderation, as with all high-mercury food. Due to its many health benefits, snapper is the main ingredient in several seafood products. Unfortunately, many individuals with food allergies or hypersensitivity may experience a severe allergic reaction after consuming snapper.
What other seafood or products should I avoid if I am allergic to red snapper?
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 red snapper are generally advised to avoid all finned fish, including bass, cod, herring, swordfish, sole, salmon, and tuna.
Additionally, individuals with an allergy to snapper 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 red snapper?
An allergy to red snapper triggers a reaction in an individual's immune system. This is because the body views specific proteins or 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 Red Snapper Allergy IgE Blood Test?
Individuals may order this Red Snapper 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
