Helicobacter pylori (H. pylori) Antibodies Blood Test, IgG
A Helicobacter pylori (H. pylori) Antibodies Blood Test is used to check for antibodies to H. pylori bacteria.
Circulating antibodies to H. pylori are predominantly of the IgG class. A systemic response of the IgA type is usually less pronounced but, if significant, may indicate a more severe inflammation. A few patients develop only antibodies to IgA. IgM antibodies are rarely found and appear to be of minor importance.
This blood test is used to detect a Helicobacter pylori (H. pylori) infection in the upper part of the small intestine (duodenum) and stomach. H. pylori may cause peptic ulcers although most people with H. pylori in their digestive systems do not develop ulcers.
If you currently have antibodies to H. pylori in your blood, it means you either are currently infected or have been infected in the past.
