RESUMO
Eradication of Helicobacter pylori (Hp) is important for the prevention and treatment of chronic gastritis, peptic ulcer and gastric cancer. The Chinese consensus on the management of Hp infection has taken "confirmed Hp infection" as an indication for eradication. The World Gastroenterology Organisation global guideline states the "test-and-treat strategy" for Hp infection. Accurate diagnosis of Hp infection is a prerequisite for standardized eradication. There are many methods to diagnose Hp infection. Each has its advantages and disadvantages. Different methods are suitable for different diseases and patients, and each method has strict requirements for reagents, equipment, testers and patients. Therefore, increasing the awareness of physicians and testers about the standardized diagnosis of Hp infection is essential to improve the diagnostic accuracy.
