Basis of the Test
To diagnose an active infection with Helicobacter pylori (H. pylori). Helicobacter Pylori H. Pylori is a spiral-shaped bacterium that attacks the lining of the stomach. Due to its spiral shape, it penetrates into the stomach and gets protected by the mucus. Hence, immune cells are not able to reach them. This bacterium causes serious stomach problems like peptic ulcers, gastritis, and most of stomach ulcers. Antigens are foreign substances that induce immune responses to produce antibodies in the human body.
