Parietal Cell Antibody, ELISA

* This is not a home test kit. You will need to visit a local lab for testing.

Also Known As

Gastric Parietal Antibody, Gastric Parietal Cell Antibody, GPA, PCA

The Purpose of a Parietal Cell AB, ELISA Test

The ELISA parietal cell antibody test is primarily used to diagnose autoimmune gastritis, a condition characterized by inflammation of the stomach lining due to the immune system’s attack on parietal cells. Low levels of intrinsic factor produced by these cells can lead to vitamin B12 deficiency, which can cause pernicious anemia, nerve damage, and other complications. This test helps healthcare providers determine the presence of parietal cell autoantibodies and their concentration, guiding diagnosis and treatment of autoimmune gastritis.

Tests Included:

Parietal Cell Antibody, ELISA (15114)

What Does the Parietal Cell Antibody Test Measure?

The ELISA parietal cell AB test measures the concentration and activity of autoantibodies against parietal cells in the blood. Parietal cell antibodies belong to a group of antibodies known as autoantibodies, produced by the immune system when it attacks the body’s cells. These antibodies can be measured using an ELISA (enzyme-linked immunoassay) test, which involves mixing the patient’s blood sample with a specific antigen. If the patient has autoantibodies against the antigen, they will bind to the antigen, and the test will show a color reaction. The intensity of the color reflects the concentration of the autoantibodies in the blood.

Who Should Take a Parietal Cell Antibody, ELISA Test?

The parietal cell AB ELISA test is recommended for people with symptoms associated with autoimmune gastritis or vitamin B12 deficiency. These may include fatigue, weakness, numbness, tingling, and neurological problems related to vitamin B12 deficiency. Other people who may require the test include those with a family history of autoimmune gastritis, pernicious anemia, or other autoimmune disorders.

Parietal Cell Antibody Test Preparation

There aren’t any special instructions to follow before taking the parietal cell antibody ELISA lab test.

ELISA Parietal Cell Antibody Test Results

A negative, or normal, result means that no autoantibodies were detected in the blood. Normal values range from 0 to 20 U/mL. Higher results indicate a greater concentration of these antibodies, indicating a more severe autoimmune gastritis. A Personalabs doctor can discuss your results and offer recommendations during a telehealth visit.
