This stool antigen test detects Helicobacter pylori (H. pylori), the bacterium responsible for most stomach ulcers and chronic gastritis. Unlike the breath test, this version uses an enzyme immunoassay (EIA) on a stool sample, making it a convenient alternative when a breath test is not feasible. It is highly accurate for both initial diagnosis and confirming successful eradication after antibiotic treatment. H. pylori infects roughly half the world's population, though many carriers are asymptomatic. Testing is recommended for patients with persistent stomach pain, bloating, nausea, or a history of ulcers.
