Eosinophil Counts in Mucosal Biopsies of the Ileum and Colon: Interobserver Variance Affects Diagnostic Accuracy

Figure 4

Virtual incidence numbers of eosinophilic enteritis /colitis in adults calculated for each investigator based on 521 patients scanned for the study. Thresholds for positive diagnosis are > 50 Eosinophils per HPF in the hepatic flexure, and > 20 in the ileum or rectum [9–13].
