The Helicobacter pylori stool antigen test identifies specific proteins of the bacterium H. pylori in a stool sample. This test is a non-invasive method used to detect an active infection in the digestive tract. H. pylori is a common bacterium that can colonize the stomach lining, potentially leading to inflammation, ulcers, and, in some cases, an increased risk of gastric cancer. Detecting these antigens directly indicates the presence of the live organism. The simplicity and accuracy of this test make it a valuable tool for initial diagnosis and for confirming successful eradication after treatment.
