Gastric Parietal Cell Antibody

Also known as: GPC

Gastric parietal cell antibodies (GPC) are directed against a parietal cell enzyme, the H+K+ATPase. The auto-antibody is found at high frequency in association with autoimmune gastritis and a proportion of these patients will progress to develop pernicious anaemia. Gastric parietal cell antibodies are present in over 90% of patients with pernicious anaemia (Highly sensitive, but not specific).

GPC antibodies should be looked for in:

  • Vitamin B12 deficiency
  • Macrocytic anaemia
  • Subacute combined degeneration of the cord
  • Individuals with other autoimmune disease i.e. thyroid disease
