Helicobacter pylori is the most prevalent bacterial infection, affecting half of the world's population, with a high morbidity and mortality rate.1,2 Several invasive and noninvasive testing procedures are available, and their selective use serves the specific needs of diverse clinical scenarios. For gastric cancer prevention, mass screening is necessary and requires a noninvasive, rapid, accurate and cost-effective test. For this purpose H pylori serology currently seems to be the preferred noninvasive diagnostic method. Population-based testing and treatment for H pylori is cost effective in high-risk countries, but less effective in low- and medium-risk countries.3,4 Many serologic tests are available on the market, with inconsistent performance often being observed. Therefore, international guidelines recommend considering only serologic tests with high accuracy that have been validated in the respective local populations. To date, no rapid point-of-care test (POCT) has reached a sufficient degree of accuracy.      «
