APCA; Anti-gastric parietal cell antibodies
Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.
Other risks associated with having blood drawn are slight but may include:
Less than 2% of the general population test positive for antiparietal cell antibodies. However, that percentage increases with age. Some people over age 60 may test positive for antiparietal cell antibodies.
Persons with other immune disorders such as thyroiditis and type 1 diabetes may also have antiparietal cell antibodies.
