Helicobacter Pylori (H.pylori) IgG Antibodies are immunoglobulins produced by the body’s immune system in response to an infection by the bacterium Helicobacter pylori. This bacterium commonly colonizes the stomach lining and is associated with gastrointestinal conditions like gastritis and peptic ulcers. Detection of IgG antibodies against H. pylori serves as a serological marker for past or ongoing infection. The presence of these antibodies, determined through laboratory tests, aids healthcare professionals in (HHD) assessing the patient’s immune response to H. pylori and in diagnosing associated gastric disorders.
