Description
A gastrin test measures stomach hormone levels to diagnose conditions like Zollinger-Ellison syndrome or chronic gastritis; in China, it typically costs ¥200–¥500, with ChinaMedicalHub assisting with hospital booking and interpreter support.
Main Uses
Gastrin testing is primarily used to diagnose and monitor conditions related to excessive or insufficient gastrin production. It is particularly useful in diagnosing Zollinger-Ellison syndrome, evaluating patients with recurrent peptic ulcers, and assessing the function of the stomach's G cells. Additionally, it helps in managing and monitoring treatment effectiveness in these conditions.
Normal Range
The normal range for gastrin levels in the blood is typically between 0 to 100 pg/mL, although this can vary slightly depending on the laboratory and the specific method used for measurement.
Low Values - Possible Causes
Possible causes of low gastrin values include: hypergastrinemia due to feedback inhibition, chronic atrophic gastritis, pernicious anemia, and certain medications that reduce stomach acid production such as proton pump inhibitors (PPIs).
High Values - Possible Causes
Possible causes of high gastrin values include: Zollinger-Ellison syndrome, peptic ulcer disease, renal failure, and conditions leading to decreased gastric acid secretion like atrophic gastritis or after vagotomy surgery.
