Why This Test Might Be Ordered
Your healthcare provider may request this test if you have symptoms like persistent nausea, vomiting, or unexplained weight loss, or if they suspect conditions such as gastritis, gastric ulcers, or certain types of stomach cancers. It can also be used to monitor chronic conditions affecting the stomach.
What to Expect Before the Test
No special preparation is typically needed. You may need to provide a sample of stomach fluid, often obtained through an endoscopy or similar procedure. Follow your provider’s instructions regarding fasting or other preparations.
What the Test Results Mean
Higher-than-normal counts may indicate inflammation, infection, or other stomach-related issues. Lower-than-normal counts could suggest certain medications, stomach emptying problems, or other conditions. Results are interpreted in the context of your overall health and symptoms.
Common Conditions Monitored or Diagnosed
This test can help diagnose or monitor conditions like chronic gastritis, gastric lymphoma, or other inflammatory or neoplastic processes in the stomach lining.
Reference range
Adult: 10-40 U/LN/A
No special preparation required. Avoid fatty meals before the test if possible.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance: Elevated mononuclear cells often reflect chronic inflammation or immune response in the gastric mucosa, which may correlate with conditions such as autoimmune gastritis or certain malignancies. Low counts may warrant further evaluation for underlying gastrointestinal dysfunction or medication effects.
