Gastrointestinal Infection Tests

H. pylori testing has a specific target

No gastrointestinal infection tests are currently listed in this category. The guidance below explains infection targets and digestive marker differences.

An H. pylori antigen test is directed at Helicobacter pylori. It is a different test from a fecal occult blood test, which checks for blood in stool rather than an infection organism. Choose according to the question being investigated, without assuming a shared sample type.

Check the specimen instructions

Read the selected product's intended use, sample collection method, storage conditions and reading window. An antigen result and an antibody result are different forms of evidence. The exact product description and instructions determine which test format you are considering.

Keep digestive and infection testing separate

Browse digestion and gut health tests for guidance on fecal blood and celiac screening. For a practice-focused GI test selection guide, see gastroenterology tests. The category name does not imply that a kit checks for norovirus, rotavirus or every possible cause of digestive symptoms.
