Description
Pepsinogen is a precursor of protease secreted by gastric mucosa, which can be divided into pepsinogen I (PG I) and pepsinogen II (PG II). Serum pepsinogen can accurately display the symptoms and functions of gastric mucosa. The detection of PG, especially the ratio of PG I/PG II and the level of PG I, is very valuable for the diagnosis of intestinal metaplasia in chronic atrophic gastritis.
Clinical significance
✔ Dynamic monitoring of individual gastric mucosal function
✔ Screening for Helicobacter pylori (HP) infection in gastric ulcer atrophic gastritis
✔ Evaluation of HP therapeutic efficacy
✔ The determination index of peptic ulcer recurrence cure
