Gastric Parietal Autoantibodies Blood Test

About this test

The Gastric Parietal Atntibodies test measures the presence of antibodies against the parietal cells of the stomach. This means that the body's immune sytstem is attacking the cells which make intrinsic factor which is necessary for the absorption of vitamin B12 from our food. 

Gastric parietal antibodies are present in individuals with autoimmune gastritis and pernicious anaemia. However they are not specific for these conditions, as they may be also found in healthy individuals, particularly with increased age, and in those with other autoimmune conditions.

Some individuals with gastric parietal autoantibodies may remain asymptomatic, but a small proportion may go on to develop pernicious anaemia.

If the screen for gastric parietal autoantibodies is positive then antibodies to intrinsic factor should be be performed. Full blood count and vitamin B12 levels should be used to aid diagnosis of pernicious anaemia and for monitoring.

Who is this test for?

This test is for individuals who have been diagnosed with vitamin B12 deficiency and wish to identify whether an autoimmune condition is the cause.
