Egg Yolk Allergy IgE Blood Test
The egg yolk allergy blood test measures the amount of allergen-specific IgE antibodies in the blood in order to detect an allergy to egg yolks.
An egg yolk allergy is usually more prominent in adults, although it can affect individuals of all ages. Individuals that are 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.
Items containing eggs and eggs themselves should be avoided if an individual is allergic.
Following is a list of common foods that contain eggs:
- Processed meats
- Salad dressing
- Baked goods
- Breaded foods
- Cream-based foods
- Tartar sauce
- Egg noodles
- Ice cream
Ingredients to be aware of:
Like every allergy, an egg yolk 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.
Symptoms of an allergy typically occur a few minutes to a few hours after exposure. Allergy symptoms vary from one individual to the next ranging from mild to severe reactions. Some commons signs of an allergy can include:
- Shortness of breath, difficulty breathing
- Redness of the skin
- Facial swelling
- Stuffy or runny nose
