An antiparietal cell antibody test is a blood test that helps to diagnose pernicious anemia, the most common cause of vitamin B12 deficiency.
The normal result is called a negative result. But it should be noticed that in some cases a negative test result does not necessarily mean that a person does not have pernicious anemia. At least 10% of those affected will not have parietal cell antibodies.
Positive results may indicate:
- Atrophic gastritis (inflammation of the stomach lining)
- Gastric ulcer
- Diabetes
- Thyroid disease
- Pernicious anemia
