OBJECTIVE: To establish the utility of the IPEN ureasa test or breath test with C14, in the detection of Helicobacter pylori infection in dyspeptic patients at the HNCH. MATERIAL AND METHODS: 31 dyspeptic patients that attended the outpatient GI clinic during September2004 were included. All of them had an upper endoscopy , gastric biopsies, and a Breath Test with C14, done at the IPEN (Peruvian Institute of Nuclear Energy) . The diagnosis of HP infection was based on the histopathology report. RESULTS: Of the 31 Breath Test , one was a false negative and in 30 there was a good correlation with the biopsies results , 23 demonstrated the HP infection and in 7 this was not present. CONCLUSION: The IPEN Breath Test showed in this study a sensibility of 96.6 % and a specificity of 100% , demonstrating that is a very useful diagnostic tool for HP infection.
