Helicobacter pylori (H. pylori) IgM,IgG,IgA

Aid in the diagnosis of acute and chronic H. pylori infections in patients with gastric and duodenal disease. Current studies suggest that H. pylori IgM testing should be performed concomitantly with H. pylori IgA and/or IgG tests for accurate diagnosis of Helicobacter pylori infection. 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 an early infection. Antibodies to IgG are the most useful for monitoring treatment.
