About Our Yeast Allergy Test

Note: Fasting is not required for this test.

This IgE antibody allergy test uses a blood sample to determine if you are allergic to Yeast (also known as baker's yeast or brewer's yeast).

Yeast is a microscopic, single-celled fungus. The most common form is Saccharomyces cerevisiae, which is the principal variety used in most bakeries and breweries. Being allergic to yeast is not the same thing as being intolerant of yeast. Yeast allergies occur when the body identifies the yeast as a harmful invader. When this happens, the body recruits the immune system to fight off the yeast. Yeast intolerance occurs only in the digestive tract and results in gastrointestinal problems like vomiting, nausea, and diarrhea. If you're experiencing digestive problems, you may have a yeast intolerance. 

People who suffer from allergic reactions to yeast can experience symptoms that range from mild to severe. Symptoms of a yeast allergy may include:

  • Abdominal bloating
  • Dizziness
  • Hives and psoriasis
  • Joint pain
  • Difficulty breathing
  • General malaise
  • Anaphylactic Shock

Yeast is extremely prevalent in a multitude of food products. If you believe you are allergic to yeast, it is best to avoid the following:

  • Breads and baked goods
  • Beer, wine, and ciders
  • Vinegar
  • Cereals

Yeast may be a hidden allergen in mayonnaise, ketchup and other processed foods, particularly those enriched with B-complex vitamins. Yeast-derived products include flavor enhancers, flavorants (especially in smoke-flavored meats), enzymes (e.g. to reduce lactose in milk), and ingredients in vitamin and mineral supplements, other pharmaceuticals and cosmetics.
