Venn diagram to present the affiliation of each diagnostic test for H. pylori infection. A total of 100 patients were enrolled, 49 of them were H. pylori infection “triple” negative. The CLO test (CLO) positive patients (n = 26) also had UBT positive and IgG serologic test (IgG) positive. And all UBT-positive patients (n = 30, equals 26 and 4) had IgG test positive. A total of 21 patients only had IgG test positive but UBT and CLO tested negative. The group of a combination of two positive tests overlapped the group of UBT positive.
