Gastroenterology

Organize GI testing by the clinical question

No gastroenterology tests are currently listed in this category. The guidance below explains GI test selection by clinical question.

Fecal blood, an infection antigen and a celiac-related antibody are different targets. When evaluating a gastroenterology test, compare its exact marker, permitted specimen, intended user and role within the wider assessment. One result cannot replace the other test types.

Read the test documentation

Check sample collection, required components, storage and result interpretation for the chosen model. A screening result does not identify the cause of symptoms or establish that further investigations are unnecessary.

For product-purpose navigation, see digestion and gut health test selection. For an infection-specific question, use gastrointestinal infection tests. The test's own intended use determines whether it fits the clinical workflow.
