Understanding Lab Tests for Gastric Adenocarcinoma
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Gastric adenocarcinoma is the most common type of stomach cancer, typically diagnosed through imaging studies, endoscopy, and tissue biopsy. While there is no single blood test that can directly diagnose gastric adenocarcinoma, laboratory testing plays a fundamental role in assessing risk factors and monitoring conditions that may predispose individuals to developing this cancer.
Recommended Test
Parietal Cell Antibody, ELISA
This test detects antibodies against parietal cells in the stomach lining. The presence of these antibodies can indicate autoimmune gastritis, a condition that causes chronic inflammation of the stomach. While not directly causing cancer, this chronic inflammatory process can increase the risk of developing gastric adenocarcinoma over time, making this test valuable for risk assessment and monitoring.

Why Blood Testing is Important for Cancer Risk Assessment
Certain autoimmune conditions and chronic inflammatory processes can increase the risk of developing gastric adenocarcinoma over time. Blood tests can identify these underlying conditions, allowing for closer monitoring and early intervention strategies that may help reduce cancer risk.
Understanding the Connection
Chronic inflammation from autoimmune conditions like pernicious anemia and autoimmune gastritis can create an environment in the stomach that, over many years, may increase the likelihood of cancerous changes in the gastric tissue. Identifying these conditions early allows healthcare providers to implement appropriate monitoring strategies.
Important Considerations

If gastric adenocarcinoma is suspected, additional diagnostic procedures including imaging and endoscopy will be necessary.
