Yeast (f45) IgE details

What Yeast (f45) IgE shows

This test measures IgE antibodies specific to Saccharomyces cerevisiae, the yeast used to make bread, beer and wine, which is also present in some fermented foods and supplements. It can help look into symptoms such as hives, itching or digestive upset after eating yeast-containing foods. True yeast allergy is uncommon, and some people with skin conditions such as atopic dermatitis show sensitization without clear food reactions. A positive result shows sensitization, not necessarily a clinical allergy. Results are interpreted against your symptoms and history, rather than as a reason to remove foods on their own.
