Why This Biomarker Matters

Baker's yeast antibodies may indicate yeast sensitivity, celiac disease, or inflammatory bowel conditions. Results should be interpreted alongside symptoms and other testing.

Overview

This test detects IgA antibodies against baker's yeast (Saccharomyces cerevisiae), which may indicate either an immune response to yeast or potential yeast sensitivity. Baker's yeast is common in bread and fermented foods. IgA antibodies are produced in mucosal tissues like the gut and suggest a localized immune response. Elevated levels may be associated with celiac disease, inflammatory bowel disease, or yeast sensitivity, though results require clinical correlation.
