Detection of antibodies to gliadin, one of the major protein components of gluten, is a sensitive assay useful in diagnosing celiac disease. However, gliadin antibodies may be found in individuals without celiac disease; thus gliadin antibody assays are less specific than assays measuring antibodies to endomysium and transglutaminase. Recent work has revealed that gliadin-reactive antibodies from celiac patients bind to a very limited number of specific epitopes on the gliadin molecule. Further, deamidation of gliadin results in enhanced binding of gliadin antibodies. Based on this information, assays using deamidated gliadin peptides bearing the celiac-specific epitopes...

Please do not exercise prior to testing. It is best that your blood is taken in a rested state.
Note: Turn around times on results are an estimate and are not guaranteed. The lab may need additional time due to holidays, confirmation/repeat testing, etc. You can contact us to discuss when your results should be ready and we will contact the lab on your behalf immediately.
