Serum TG2-IgA titers in participants with and without a biopsy-verified diagnosis. Serum TG2-IgA levels in participants with a biopsy-verified diagnosis (left panel, n = 173) had a similar distribution to those in participants who were not biopsied (right panel, n = 103, light-blue rhombi). The horizontal line indicates median TG2-IgA titers (U/mL). TG2-IgA tissue transglutaminase 2-IgA antibodies.
