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.

Preparation

Preparation varies by test; some require fasting or avoiding certain foods or medications beforehand. Always follow the specific instructions provided by the collection lab.

How results are reported

Results are reported as values for each marker, often with a reference range for comparison. Reference ranges can differ between laboratories, so your results should be interpreted in the context of the lab that performed the test.

Before you go

  • Whether any medications or foods should be avoided before collection
  • The specific sample type and collection kit required for each test
