Yeast Allergy IgE Blood Test

What is the purpose of this test?

Order this Yeast Allergy IgE Blood Test to measure the IgE antibody levels in the blood to help detect an allergy to yeast. Yeast is a fungus used as an active ingredient in many foods and drinks, especially baked goods (baker's yeast) and alcoholic beverages (brewer's yeast). However, many other forms of yeast, including Candida and others, live naturally in the body. 

How do I manage my yeast allergy?

Individuals with yeast allergies may also be allergic to other types of yeast, such as baker's yeast enolase, brewer's yeast, and Candida albicans. This cross-reactivity occurs when the immune system identifies similarly structured or biologically related proteins or components in different substances, thus triggering an adverse reaction.

Because yeast can be found in the foods we eat and the surrounding environment, individuals must take many preventative steps to reduce an allergic reaction. For example, avoiding an adverse response to yeast may require eliminating foods that contain yeast, such as:

• Baked goods (muffins, biscuits, croissants, or cinnamon rolls)
• Alcoholic beverages
• Bread (sourdough)
• Specific multivitamins
• Cereal products
• Stocks, bouillion cubes, and gravies
• Vinegar and vinegar-based products (pickles or salad dressing)
• Cured meats and olives
• Mushrooms
• Fermented foods (kimchi, sauerkraut, buttermilk, synthetic cream, and yogurt)
• Dried fruits
• Certain fruits (blackberries, grapes, strawberries, and blueberries)
• Soy-based products (soy sauce, miso, and tofu)
