We evaluated the accuracy of the diagnosis of celiac disease (CD) performed in the community clinical setting compared with that of an academic experienced center.

We detected a divergent diagnosis between the two practice settings in 46.3% of available cases with a significant overdiagnosis of CD in the community (p < 0.0001). Congruent serology results were demonstrated in 72.2% of cases. Our study detected a high rate of histopathological and serological misdiagnosis of CD in community practice which may have profound negative impact on patients.
