Helicobacter pylori antigen IVD, antibody

Helicobacter pylori antigen in-vitro diagnostic (IVD) antibody tests detect the presence of antibodies in a patient’s blood or serum that target the *Helicobacter pylori* bacterium. Clinically, these tests help diagnose infections linked to gastric ulcers, gastritis, or other gastrointestinal conditions by identifying immune responses to the pathogen.

These devices are typically regulated as IVDs, often requiring validation for accuracy and clinical performance. They are commonly supplied as kits for laboratory use, including reagents, controls, and instructions for qualitative or quantitative analysis, though some may be point-of-care formats.
