Antiparietal Cell Antibodies

Antiparietal cell antibodies are proteins produced by the immune system that mistakenly target and attack the parietal cells in the stomach. These cells are essential for producing gastric acid and intrinsic factor, which helps in vitamin B12 absorption. The presence of these antibodies can indicate autoimmune conditions, such as pernicious anemia, where the body struggles to absorb vitamin B12, potentially leading to anemia and neurological issues. Testing for these antibodies can help diagnose these conditions and guide treatment.
