Helicobacter pylori, IgM Antibodies
Test ID:
705074
CPT code:
86677
Synonyms:
Helicobacter pylori Antibodies, IgM
Anti-Campylobacter Antibodies, IgM
Anti-H pylori, IgM
Clinical Use:
Diagnose early H pylori infection in patients with gastric and duodenal disease. 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. Antibodies to IgM, although rare, may indicate an early infection.
Test Information:
Results of this test are for investigational purposes only. The results should not be used as a diagnostic procedure without confirmation of the diagnosis by another medically diagnostic product or procedure.
Current studies suggest that H pylori IgM testing should be performed concomitantly with IgA and IgG tests for associated diagnosis of H pylori.
