CPT code:

86677

Synonyms:

Helicobacter pyloriAntibodies, IgA
Anti-Campylobacter Antibodies
Anti-H pylori, IgA

Clinical Use:

Diagnose H pylori infection in patients with duodenal disease and for monitoring the eradication of H pylori following antimicrobial therapy; identify the small percentage of H pylori-infected patients who fail to mount a systemic IgG response and demonstrate IgA antibodies only and for those patients who have chronic mucosal infections

Test Information:

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.
