Helicobacter pylori blood test accurate?

Helicobacter pylori detection is generally detected by breath test or gastroscopy. Blood sampling can only detect Helicobacter pylori antibody, and the accuracy is poor. Helicobacter pylori infection is closely related to chronic gastritis, peptic ulcer and gastric cancer. Helicobacter pylori can be transmitted through the faecal route, which is also the reason why many people show Helicobacter pylori. Helicobacter pylori infection patients excreta, vomit, saliva or feces can contaminate the food of susceptible people, causing infection of others. In ordinary life, the most common way of infection is to eat together. If there is Helicobacter pylori infection, it is recommended to see a specialist to determine whether eradication treatment is needed.
