Pernicious anemia (PA) is the final stage of autoimmune gastritis and characterized by vitamin B12 deficiency.1 Its definitive diagnosis is important because the patients need lifelong parenteral vitamin B12 treatment.2
PA is associated with two autoantibodies that can be used for diagnostic testing:1
- Antibodies directed to parietal cells that produce the vitamin B12-transporting protein called intrinsic factor.
- Antibodies directed to the intrinsic factor, blocking its capability to transport vitamin B12 through the ileum wall.
The simultaneous determination of antibodies to parietal cells and those to intrinsic factor create a higher probability in the diagnosis of PA.1,2
