Understanding Lab Tests for Mucosa-Associated Lymphoid Tissue (MALT) Lymphoma
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Mucosa-Associated Lymphoid Tissue (MALT) lymphoma is a rare type of non-Hodgkin lymphoma that develops from immune system cells. While there is no single blood test to diagnose MALT lymphoma itself, which typically requires tissue biopsy and imaging studies, blood testing plays a crucial supporting role in identifying underlying causes and monitoring overall health.
Recommended Test
H. Pylori Antigen Stool
This test is essential for detecting H. pylori infection, which is a major risk factor for gastric MALT lymphoma development. Since chronic H. pylori infection can trigger this rare immune system cancer in the stomach lining, identifying and treating the bacterial infection is crucial for both prevention and treatment of gastric MALT lymphomas.

The Connection Between H. Pylori and MALT Lymphoma
Gastric MALT lymphomas are strongly associated with chronic H. pylori bacterial infections. This persistent infection can cause chronic inflammation of the stomach lining, which over time may lead to the development of MALT lymphoma. Testing for H. pylori is therefore fundamental in the evaluation and management of gastric MALT lymphoma.
Why This Testing Matters
Early detection of H. pylori infection allows for prompt antibiotic treatment, which can not only prevent the development of MALT lymphoma but may also help treat early-stage gastric MALT lymphomas. In many cases, eradicating H. pylori infection can lead to regression of the lymphoma, making this testing a critical component of both prevention and treatment strategies.
