2089. Helicobacter pylori, total antibodies
Description
Helicobacter pylori (H. pylori) is a gram-negative, spiral-shaped bacterium that can colonize the lining of the stomach and duodenum and cause inflammation.
Serological studies reveal specific immunoglobulins in the blood directed against H. pylori. H. pylori infection is accompanied by the development of a local and systemic immune response. Following a transient increase in the titer of class M immunoglobulins (IgM), a prolonged and significant increase in IgG, as well as IgA antibodies in the blood serum, follows. IgG are found in 95-100% of cases of H. pylori infection. The sensitivity of H. pylori serological tests in children is lower.
