Why This Biomarker Matters

Positive IgE indicates a potential true allergy to yeast. This helps guide avoidance of fermented foods and baked goods, preventing allergic reactions.

Overview

Baker's yeast (Saccharomyces cerevisiae) IgE antibodies indicate a potential allergic reaction to this common yeast used in baking and fermentation. An IgE antibody test detects whether your immune system has mounted an allergic response to yeast proteins. Elevated IgE suggests a true IgE-mediated yeast allergy, which can cause itching, swelling, hives, or in severe cases, anaphylaxis. This helps distinguish yeast allergy from yeast intolerance or sensitivity.
