The H. pylori Stool Antigen Test is a noninvasive diagnostic test used to detect infection with Helicobacter pylori, a common bacterium that lives in the digestive tract. This organism is uniquely adapted to survive the harsh acidic environment of the stomach and is a leading cause of chronic stomach inflammation and ulcers. When H. pylori infects the stomach lining, it can weaken the protective mucosal barrier that shields the stomach from acid. This disruption can lead to gastritis, stomach ulcers, or ulcers in the duodenum, often causing symptoms such as abdominal pain, bloating, nausea, or indigestion. Although many people infected with H. pylori never develop noticeable symptoms, long-term infection is associated with serious complications, including recurrent ulcers, chronic gastritis, and an increased risk of stomach cancer and certain lymphomas. Early detection allows for timely treatment that can eliminate the infection and reduce these risks. This stool-based test detects antigens produced by H. pylori, indicating an active infection or one that occurred within the past year. Because it does not require endoscopy, it offers a convenient and reliable option for both diagnosis and post-treatment monitoring. What Is Included In This Test? This test analyzes a stool sample for the presence of H. pylori antigens. Your results can help: • Detect an active H. pylori infection • Identify the cause of chronic gastritis • Support the diagnosis of stomach or duodenal ulcers • Confirm recent H. pylori exposure • Monitor response after treatment Why Does This Test Matter? H. pylori infection is a common but often overlooked cause of persistent digestive symptoms. Without testing, infection may go untreated for years while continuing to damage the stomach lining. Early identification allows for targeted antibiotic treatment that can eradicate the bacteria and promote healing of the stomach and intestinal lining. Treating H. pylori reduces the risk of ulcer recurrence and long-term complications. This test is also useful after treatment to confirm that the infection has been successfully cleared. Persistent infection after therapy may require additional or alternative treatment strategies. By offering a noninvasive and accurate way to detect infection, this test supports faster diagnosis, effective treatment, and improved digestive health outcomes. Who Should Consider This Test? This test is ideal for individuals with symptoms or conditions associated with stomach inflammation or ulcers. You should consider this test if you: • Have ongoing stomach pain or indigestion • Experience nausea, bloating, or frequent heartburn • Have a history of stomach or duodenal ulcers • Have chronic type B gastritis • Need confirmation of H. pylori eradication after treatment • Want a noninvasive alternative to endoscopy Testing helps uncover a common and treatable cause of chronic digestive discomfort.
