What's the use of gastrin test?

Gastrin examination is used to judge whether there is antral mucosa hyperplasia, diagnose chronic atrophic gastritis, and identify gastrinoma.

1. When judging whether there is antral mucosa hyperplasia

, gastrin examination can judge whether there is abnormal hyperplasia of antral mucosa according to serum gastrin level, which is helpful for diagnosis of disease.

2.

When diagnosing atrophic gastritis, parietal cell antibody may be positive, resulting in parietal cell atrophy, decreased gastric acid secretion, and increased gastrin level after G cells in gastric antrum are stimulated.

3. Identification of gastrinoma

Gastrin tumor formation can cause D cell proliferation in patients, secrete a large amount of gastrin, and lead to extreme proliferation of parietal cells, which can assist in diagnosis of gastrinoma.
