Whole Egg Allergy IgE Blood Test
The whole egg allergy blood test measures the amount of allergen-specific IgE antibodies in the blood in order to detect an allergy to both egg yolks and whites. An individual can be allergic to egg yolks or whites or both. This test evaluates an individual's allergic reaction to the entire egg and does not distinguish between yolks and whites.
Description
As a part of a healthy diet, eggs can be a great source of protein. However, some individuals can be allergic to proteins present in either egg yolk or egg white, or even both. Individuals with an egg allergy must avoid egg in all forms. It is not possible to separate the egg white from the yolk entirely.
Like every allergy, an egg allergy causes a reaction in the immune system. When contact is made with the allergen, the body views it as toxic and becomes sensitized, producing IgE antibodies against these contaminants. These antibodies trigger the release of histamines, which will cause the symptoms of an allergic reaction.
Eggs are one of the most widely recognized food allergens. Individuals with an egg allergy could be allergic to other types of eggs, including duck, goose, quail, or turkey.
Symptoms of an allergy typically occur a few minutes to a few hours after consuming eggs or foods that contain eggs. Allergy symptoms vary from one individual to the next ranging from mild to severe reactions. Some commons signs of an egg allergy can include:
- Vomiting
- Diarrhea
- Stomach cramps
- Indigestion
- Tightness in the throat, or hoarse voice
- Wheezing
- Repetitive cough
- Shortness of breath, difficulty breathing
- Weak pulse
- Hives
- Dizziness
- Swelling of the tongue and/or lips
- Confusion
- Pale or blue coloring of the skin
