AGPA are commonly associated with pernicious anemia and chronic atrophic gastritis where they occur in about 90% and 50% of cases, respectively. Although healthy individuals may have gastric parietal cell antibodies, this finding may reflect asymptomatic atrophic gastritis. Negative findings for gastric parietal cell antibodies provide strong evidence for excluding pernicious anemia.
