The three gastric function values exceed the normal range, suggesting the possibility of gastritis, gastric ulcer, and gastric malignancy. Gastric function refers to gastrin 17, pepsinogen I and pepsinogen II. The normal value of serum gastrin (G-17) is 1.7-7.6 pmol/L, which is secreted by the G cells in the gastric sinus, and it is a key indicator of the damage of gastric mucous membrane; the normal value of pepsinogen I is 67-200 ng/ml, and that of pepsinogen II is 0-15 ng/ml, both of which can reflect the function and status of gastric mucous membrane and the secretion of pepsin. The normal value of pepsinogen I is 67~200 ng/ml, and the normal value of pepsinogen II is 0~15 ng/ml, both of which can reflect the function and state of gastric mucosa and secretion of pepsin. If the test result is out of the normal range, it suggests the possibility of gastritis, gastric ulcer, malignant tumor of the stomach, please find a doctor for further diagnosis and treatment in time to avoid delaying the condition.
