In this regard, breath tests and stool tests are extensively used. Hardly few studies have been done to establish their better diagnostic accuracy.<br> <strong>Objectives.</strong> Hence, this study was undertaken to compare urea breath and stool antigen tests for their accuracy in identifying H pylori infection.<br> <strong>Methods. </strong>One hundred thirty-nine abdominal pain patients who were diagnosed with rapid urease test underwent stool antigen testing and urea breath test.<br> <strong>Results. </strong>Based on the rapid urease test, for Urea Breath Test Sensitivity, specificity, positive predictive values, negative predictive values, and Accuracy were76% 34%, 60%, 52%, and 58%, and by the HpSA Test Sensitivity, specificity, positive predictive values, negative predictive values and Accuracy were75%, 33%, 60%, 49%, and 57%. There were no significant differences in the performance of these tests.<br> <strong>Conclusions.</strong> Urea Breath and HpSA Tests have the same diagnostic accuracy in H. Pylori Infection.</div> Helicobacter Pylori, Urea Beath test, Stool Antigen Test 0 0 http://aapjournal.com/browse.php?a_code=A-10-32-1&slc_lang=en&sid=1 Vinodh RS physio_vinodh2424@vimsmail.com 100319475328460087 100319475328460087 Yes Department of Physiology, Vydehi Institute of Medical Sciences and Research Center, Bangalore, India
