Biomarkers
Start with the primary markers, then add the companions that change how the primary result reads. Each link cites its source.
IgAPrimary marker
The ACG guideline measures total IgA at the same time to detect IgA deficiency.
Tests: Labcorp 15, Quest Diagnostics 8
t-Transglutaminase (tTG) IgAPrimary marker
The ACG guideline names tissue transglutaminase IgA as the serologic test for celiac disease.
Tests: Labcorp 9, Quest Diagnostics 2, with ranges on the biomarker page
Deamidated Gliadin Abs, IgGCompanion marker
With IgA deficiency, the ACG guideline uses IgG serology such as deamidated gliadin peptide IgG.
Tests: Labcorp 6
Endomysial Antibody IgACompanion marker
The ACG guideline pairs a high tTG IgA with a positive endomysial antibody on a second sample in some diagnoses.
Tests: Labcorp 4
