Antiparietal cell antibodies
Definition

This is a test to measure the presence of antibodies against the parietal cells of the stomach. The parietal cells secrete intrinsic factor and stomach acid.


Alternative Names

APCA; Anti-gastric parietal cell antibodies


How the test is performed

Blood is drawn from a vein and sent to the lab, where the serum (liquid portion of the blood) is separated from the cells. A sample of the serum is placed on a slide with samples from a mouse kidney and stomach, which contain parietal cells. If the patient's serum has parietal cell antibodies, they will react with the parietal cells on the slide.


How to prepare for the test
