Introduction: all of the available tests for the diagnosis of H. pylori have differences in their sensibility and specificity. The purpose of this study is to determine the developmental index, sensibility, specificity and predictable values of four invasive methods, using the case definition as a referential technique; positive culture o concordance of at least two processes of positive diagnostics. Methods: five biopsies were taken among seventy two patients, distributed for PCR-ureC, culture, quick ureic test (PRU) and histological examination (EH). Results: the developmental index (ID), sensibility, specificity and predictive measures showed differences. The couple EH-PCF was considerably effective, presenting the greatest values of analyzed indexes. The prevalence of infection was of 86.1%. Conclusion: in order to establish the true status of the infection by H. pylori, it is necessary to use the criteria by case definition.
