Numerous invasive and non-invasive tests are available in the detection of Helicobacter pylori. Endoscopy-based tests that include rapid urease test, histological examination and culture are important generally in the assessment of H. pylori status before eradication therapy. Recently, several new endoscopy-based diagnostic methods have been developed aiming at rapid and accurate detection of the organisms. It would be possible to diagnose H. pylori infection in treated patients by using these new highly sensitive tests. Although the diagnosis of H. pylori infection itself is possible by using non-invasive diagnostic tests, endoscopy-based tests provide not only the diagnosis of the organisms, but also the exclusive information such as treatment indications and the susceptibility for the antimicrobial drugs. Recently, new triple therapy including clarithromycin has been widely performed in Japan. Along with an increase in the prevalence of the antibiotic-resistant strains, culture may become a more important diagnostic method in the future. The inappropriate application of the tests may increase the potential risk of the misdiagnosis and the treatment failures. The diagnostic method should be selected by taking into account the circumstances in which a diagnosis is to be performed.
