Why This Biomarker Matters
Elevated levels indicate celiac disease or gluten sensitivity. This helps confirm diagnosis and monitor whether you're successfully avoiding gluten in your diet.
Understanding Your Results
Normal Range
0 – 1 [arb'U]/mL
Overview
This test measures IgA antibodies against gliadin, a protein component of gluten. Your immune system produces these antibodies when exposed to gluten in people with celiac disease or gluten sensitivity. Elevated levels suggest an immune reaction to gluten in wheat, barley, and rye. This test helps diagnose celiac disease and monitor adherence to a gluten-free diet in diagnosed individuals.
