Do you need to do a gastric function test after a gastroscopy to confirm the diagnosis of chronic superficial gastritis?

After gastroscopy to confirm the diagnosis of chronic superficial gastritis, gastric function tests are also required. Gastric function tests include serum pepsinogen and serum gastrin tests, as well as Helicobacter pylori tests. Sometimes gastroscopy is not completely accurate in reflecting mucosal atrophy or intestinal epithelialization, and gastric function tests can further examine and alert the clinician to possible lesions and influence the next step in treatment. Serum pepsinogen is a good indicator of the acid secretion function of the mucosa of the gastric body, and it can also indicate atrophy of the mucosa of the fundic glands. Serum gastrin test is a sensitive indicator to reflect the secretion ability of the gastric sinus, which can indicate the atrophy of the mucosa at the gastric sinus. Helicobacter pylori test also needs to be perfected, Helicobacter pylori is a common cause of chronic gastritis, perfect this test to provide evidence for the next step in the treatment, the more common clinical test is carbon 13 or carbon 14 breath test. Patients with chronic superficial gastritis should further improve the examination and standardize the treatment under the guidance of the doctor.
