What is the purpose of this test?
Order this Whole Egg Allergy IgE Blood Test to measure the IgE antibody levels in the blood to detect an allergy to egg yolks and whites. Eggs are one of the most widely recognized food allergens. In addition, individuals with an egg allergy could be allergic to other types of eggs, including duck, goose, quail, or turkey. As a part of a healthy diet, eggs can be a great source of protein. However, some individuals can be allergic to proteins in either egg yolk, egg white, or even both. Therefore, individuals with an egg allergy must avoid eggs in all forms. Unfortunately, it is not possible to separate the egg white from the yolk entirely.
Individuals with an adverse reaction to egg yolks and whites may also experience the same response after ingesting chicken since they may have some allergens (proteins) in common. Therefore, this Whole Egg Allergy Blood Test may help screen for an allergy to whole eggs and aid healthcare providers in developing a management and treatment plan.
What other food products should I avoid if I have an egg allergy?
Individuals allergic to eggs should avoid not only it but also avoid egg-based, including:
- Baked goods
- Premade salads
- Frozen meals that may contain eggs
- Avidin globulin
- Egg (dried, powdered, solids, white, yolk)
- Meringue (meringue powder)
What causes an allergic reaction to whole eggs?
Once an individual with a whole egg allergy ingests egg yolks or whites, it triggers a response in an individual's immune system. The immune system views specific proteins in eggs 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 Whole Egg Allergy IgE Blood Test?
Individuals may order this Whole Egg Allergy IgE Blood Test if they have experienced symptoms related to an egg 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 an egg 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
