The four tests of gastric function are the first choice screening means for early prevention, early detection, early diagnosis and early treatment of gastric cancer. The test mainly includes serum pepsinogen I(PGI), serum pepsinogen II(PGII), ratio of serum pepsinogen I to serum pepsinogen II(PGI \PGII), serum gastrin 17(G-17) and antibodies to Helicobacter pylori (HP)​.

Helicobacter pylori infection affects nearly 50% of the global population and is an important cause of chronic gastritis, peptic ulcer, gastric cancer and other diseases. Timely detection and eradication of Helicobacter pylori can reduce the risk of gastric cancer. At present, Helicobacter pylori detection methods mainly include gastroscopy, 13C or 14C urea breath test, serum Hp antibody detection and fecal Helicobacter pylori antigen detection.

Helicobacter pylori (Hp) is currently found to be the only bacteria that can survive in the stomach for a long time. It can be transmitted through oral, fecal and iatrogenic transmission.

Helicobacter pylori (Hp) infection has been a significant health problem worldwide, with infection rates as high as 50% globally.

Helicobacter pylori (Hp) is a spiral-shaped, slightly anaerobic, Gram-negative bacterium that needs very strict growth conditions.

Helicobacter pylori (H. pylori) infection often does not cause any noticeable symptoms, and many infected individuals remain asymptomatic. However, when symptoms do occur, they can vary among individuals.

Helicobacter pylori is a common bacterium that is believed to be one of the main causes of many stomach problems. The bacteria mainly reside in the gastric mucosa and can cause diseases such as gastritis, duodenitis, gastric ulcer, duodenal ulcer, and gastric cancer.

Helicobacter pylori (H. pylori) is a bacterium that inhabits the human stomach and is known to cause various gastrointestinal disorders, including gastritis, peptic ulcer disease, and gastric cancer. The infection is very common and it increases the risk of duodenal or gastric ulcers. For some patients, Helicobacter pylori infection causes gastric mucosal atrophy and dysfunction (atrophic gastritis). Atrophic gastritis is usually asymptomatic, and it causes the stomach to become acid-free, where oral microbes are able to live and produce carcinogenic acetaldehyde from sugars and alcohol.
