The Egg Yolk Allergy IgE Blood Test measures the IgE antibody levels in the blood to help detect an allergy to egg yolks.
What is the purpose of this test?
Order this Egg Yolk Allergy IgE Blood Test to measure the IgE antibody levels in the blood to detect an allergy to egg yolks. Eggs are one of the most widely recognized food allergens. As a part of a healthy diet, eggs can be a great source of protein. An egg yolk allergy is usually more prominent in adults, although it can affect individuals of all ages. Individuals allergic to egg yolks can usually safely consume egg whites without difficulty. When it comes to eggs, egg whites' proteins are more likely to cause an allergic reaction than the yolk proteins. Unfortunately, it is not possible to separate the egg yolk from the white entirely.
Individuals with an adverse reaction to egg yolks may also experience the same response after ingesting chicken since they may have some allergens (proteins) in common. In addition, individuals with an egg yolk allergy could be allergic to other types of eggs, including duck, goose, quail, or turkey. Therefore, this Egg Yolk Allergy Blood Test may help screen for an allergy to egg yolks, and aid healthcare providers in developing a management and treatment plan.
What other food products should I avoid if I have an egg yolk allergy?
Individuals allergic to egg yolk should avoid not only it but also avoid egg-based, including:
- Processed meats
- Salad dressing
- Baked goods
- Breaded foods
- Cream-based foods
- Tartar sauce
- Egg noodles
- Ice cream
- Products containing apovitillin, phosvitin, and livetin
What causes an allergic reaction to egg yolks?
Once allergic individuals ingest egg yolks, it triggers an individual's immune system response. The immune system views specific proteins in egg yolks 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 an Egg Yolk Allergy IgE Blood Test?
Individuals may order this Egg Yolk Allergy IgE Blood Test if they have experienced symptoms related to an allergic reaction. 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 an egg yolk allergy may experience one or more of the following symptoms:
- Tingling sensation near or around the mouth
- Abdominal discomfort
- Nausea or vomiting
- Itching or hives
- Difficulty breathing, swallowing, or wheezing
A severe, possibly life-threatening allergic reaction known as anaphylaxis may occur in some cases. 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
