Description:

Antiparietal Cell Antibody Test

This test measures Antiparietal Cell Antibodies in the blood.  Parietal cells are cells in the stomach which produce acid used in digestion as well as intrinsic factor, a protein which helps the body absorb Vitamin B12.  In people with an autoimmune disorder known as Pernicious Anemia, the immune system produces antibodies which attack parietal cells.  Damage to the parietal cells can inhibit the production of Intrinsic Factor which in turn prevents the body from properly absorbing vitamin B12.  B12 deficiency prevents the normal production of red blood cells which can lead to a number of health complications.

This test may be ordered when someone has symptoms of Vitamin B12 deficiency or anemia.  A Parietal Cell Antibody Test is often ordered along with a Complete Blood Count (CBC).  Additional tests such as Methylmalonic Acid, Homocysteine, Vitamin B12 & Folate or Intrinsic Factor Blocking Antibodies may sometimes be ordered as a follow-up.

Turnaround for this test is typically 2-5 business days.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
