Reference Interval
1.7 EV or less: Negative - No significant level of IgG antibody to H. pylori detected.
1.8-2.2 EV: Equivocal - Repeat testing in 10-14 days may be helpful.
2.3 EV or greater: Positive - IgG antibody to H. pylori detected, suggestive of previous exposure or active infection.  
Interpretive Data
Previously known as Campylobacter pylori, Helicobacter pylori-specificantibodies are detectable in almost all adult patients with duodenal ulcer and about 80% of patients with gastric ulcer. The prevalence of H. pylori antibodies increases with age and can be found in a significant percentage of healthy individuals over the age of 50. Positive results do not confirm the diagnosis of H. pylori-associated gastritis or duodenal ulcer, but negative results are strong evidence against these diagnoses.
