Limited value of testing for intrinsic factor antibodies with negative gastric parietal cell antibodies in pernicious anaemia: Figure 1

Abstract

This study provides evidence that testing for gastric parietal cell antibodies is an appropriate screening test for pernicious anaemia, with intrinsic factor antibodies reserved for confirmatory testing or in patients with other autoantibodies that mask the GPC pattern; B12 levels are not related to autoantibody status.
