Testing negative for H. pylori while doing gastroscopy does not require further breath test testing for the time being. Clinically used H. pylori testing methods include rapid H. pylori testing and breath test testing. Rapid H. pylori testing refers to the diagnosis of H. pylori by clamping tissues under the microscope directly on the test paper while doing gastroscopy. Breath test refers to c13 and c14 breath tests, which are commonly used to review H. pylori after treatment. Because of the infectious nature of H. pylori, it is recommended to share meals and promote the use of communal chopsticks for daily meals. A negative H. pylori test does not prove that the test is always negative, and it is recommended that the test should be combined with a pathological biopsy to make a judgment. The rapid urease test has the possibility of false negatives, so if you have digestive symptoms such as abdominal pain, bloating, belching, etc., you should consult the doctor in time in order to avoid delaying your condition.
