Helicobacter Pylori Antigen (H.Pylori) Stool Test Kit

At-home stool test for Helicobacter pylori antigen — an indicator of current infection.

What this test measures

H. pylori antigen in a single stool sample.

Why these markers matter

H. pylori is a bacterium that lives in the stomach lining. Antigen testing indicates current presence rather than past exposure, which is the distinction that matters when deciding what to do next — antibody tests can stay positive long after an organism has gone. It's commonly investigated alongside reflux, gastritis and upper digestive symptoms.

Before you collect
