Do gastroscope to be able to detect pyloric helicobacterium

Gastroscopy is an examination

of the esophagus, stomach and duodenum by inserting a flexible tubular probe into the mouth. During gastroscopy, doctors can directly observe the condition of gastric mucosa, but they cannot directly see Helicobacter pylori. Some gastric mucosa tissue samples need to be taken for biopsy, such as histopathological examination, rapid urease test, molecular biological detection, immunohistochemical detection, etc., to determine whether there is Helicobacter pylori infection.
