What this test is
These tests are a group of laboratory analyses that examine stool, blood, or breath samples to assess digestion, inflammation, infection, or malabsorption. They are often ordered together to get a broad picture of gastrointestinal health.
What it measures
- Fecal calprotectin — reflects inflammation in the digestive tract
- Fecal occult blood — detects hidden blood in stool
- Stool culture — identifies bacterial infections
- Celiac disease antibodies — screens for immune reaction to gluten
- Helicobacter pylori antigen — detects the bacterium linked to ulcers
- Pancreatic elastase — assesses pancreatic enzyme production
What the test involves
Depending on the specific test, you may provide a stool sample, a blood sample from a standard draw, or a breath sample collected after drinking a solution. The collection method is chosen by the lab based on the test ordered.
Why it is often ordered
A clinician may order these tests to investigate ongoing digestive symptoms, monitor a known gastrointestinal condition, or screen for issues such as infection or inflammation. They are typically used alongside a medical history and physical exam.
