Understanding Lab Tests for Gastric Ulcers
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Gastric ulcers are open sores that develop in the lining of the stomach, typically diagnosed through imaging studies or endoscopy. While there isn't a single blood test to diagnose gastric ulcers directly, blood testing plays a crucial role in identifying underlying causes, assessing complications, and monitoring the body's response to treatment.
Recommended Test
Gastrin
This test measures gastrin levels in the blood, a hormone that stimulates stomach acid production. Elevated gastrin levels can indicate conditions like Zollinger-Ellison syndrome or other disorders that cause excessive acid production, which is a significant contributing factor to gastric ulcer formation. Understanding gastrin levels helps identify whether hormonal imbalances are contributing to ulcer development.

Why Blood Testing is Important for Gastric Ulcers
Blood tests are fundamental for understanding the root causes of gastric ulcers and detecting potential complications. They help healthcare providers identify hormonal imbalances that may contribute to excessive stomach acid production, assess for infections like H. pylori, and monitor for signs of bleeding or anemia that can result from ulcers.
Understanding Your Results
Gastrin testing helps healthcare providers determine if excessive stomach acid production due to hormonal imbalances is contributing to ulcer formation. This information is valuable for developing targeted treatment strategies and identifying rare conditions that may require specialized care.
