Screens for antibodies against the stomach's acid-making cells — the most sensitive blood marker of autoimmune gastritis, the condition that leads to pernicious anemia. Parietal cells line the body of the stomach and make both hydrochloric acid and intrinsic factor. In autoimmune gastritis the immune system attacks them; over years the stomach lining thins (atrophic gastritis), acid production falls, iron and B12 absorption suffer, and pernicious anemia can follow. Parietal cell antibodies appear early and are found in roughly 80–90% of people with the condition, which makes this the sensitive screening test — but they also occur in some people with autoimmune thyroid disease, type 1 diabetes or Addison's disease, and in a few percent of healthy older adults, so a positive result is a reason to look further rather than a diagnosis. The intrinsic factor blocking antibody is the specific confirmatory test; gastrin rises when acid production has fallen; B12, ferritin and a CBC show whether absorption is already impaired. Consider this test for unexplained iron-deficiency anemia that does not respond to oral iron, low or borderline B12, a macrocytic anemia, or new fatigue with another autoimmune condition. A gastroenterologist confirms atrophic gastritis by endoscopy with biopsies. Run at Quest (test 262, with reflex to titer when positive). ## Biomarkers measured - Parietal Cell Antibody ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $139.99 | $145.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | BioReference (NY & NJ) | $139.99 | $145.99 | New York and New Jersey orders route here automatically | Rhode Island is not served.
