[Study of urease test or breath test (BT) and correlation with gastric biopsy to detect helicobacter pylori (Hp) in dyspeptic patients at "Hospital Nacional Cayetano Heredia hospital" (HNCH)--Lima].
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.


METHODS
31 dyspeptic patients that attended the outpatient GI clinic during September 2004 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.


CONCLUSIONS
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.
