The Helicobacter Pylori Antibody test is a simple blood test used to check for a past or current infection with H. pylori, a common bacterium that affects the stomach. When this germ enters your body, your immune system produces specific antibodies that remain detectable in the blood. By measuring these antibodies, our lab helps your doctor determine whether H. pylori may be the cause of symptoms such as stomach pain, acidity, bloating, or suspected ulcers. While additional tests may be needed to confirm an active infection, this test provides critical, early insight, guiding your doctor toward the right treatment and long-term digestive health.
