The Helicobacter pylori Urea Breath Test detects H. pylori infection, a common cause of ulcers and gastritis. After drinking a urea solution, breath samples are analyzed for carbon dioxide changes caused by the bacteria. A positive result indicates active infection, while a negative shows no evidence of H. pylori. Doctors use this noninvasive test to diagnose infection, confirm eradication after treatment, and monitor gastrointestinal health.

The Helicobacter pylori Antigen Stool Test detects H. pylori proteins in stool to diagnose active infection. H. pylori is a common cause of gastritis, ulcers, and increased stomach cancer risk. Doctors order this test for patients with abdominal pain, nausea, bloating, or indigestion. Noninvasive and accurate, results confirm active infection and are also used to monitor treatment effectiveness and eradication of H. pylori bacteria.

The Gastrin Test measures gastrin hormone levels in blood, which regulate stomach acid production. Elevated levels may indicate Zollinger-Ellison syndrome, gastrinoma, pernicious anemia, or chronic atrophic gastritis. Doctors order this test for patients with recurrent ulcers, abdominal pain, or unexplained diarrhea. Results help evaluate abnormal acid production, detect tumors, and guide treatment for gastrointestinal and metabolic conditions.
