Parietal Cell Antibody

The Parietal Cell Antibody test detects autoantibodies directed against gastric parietal cells—cells that produce stomach acid and intrinsic factor, a protein essential for vitamin B12 absorption. This serum-based immunoassay (typically reporting IgG antibodies and a titre) helps identify autoimmune gastritis and the risk of pernicious anemia by indicating immune-mediated damage to the stomach lining.

This test is useful for patients with unexplained vitamin B12 deficiency, macrocytic anemia, or neurological symptoms suggestive of B12 malabsorption, and for people with other autoimmune conditions. Offered as a convenient home collection service with accredited Dubai labs, results are reported quickly to support timely clinical decisions such as B12 replacement therapy, further gastroenterology evaluation, or testing for intrinsic factor antibodies and endoscopic assessment when indicated.
