A glutamic acid decarboxylase (GAD) antibody test looks for a type of autoimmune antibody typically associated with diabetes. GAD is an enzyme that plays a role in nervous system function. Certain autoimmune disorders can cause the production of GAD autoantibodies which attack cells in the pancreas responsible for the production of insulin. The inability to properly produce insulin can lead to the development of diabetes. A GAD antibody test can help determine which type of diabetes a person has. In most cases, a person with type 1 diabetes will show elevated GAD antibody levels. A GAD antibody test is typically ordered to aid in diagnosing a person with diabetes and determining which type they have. It can also be used to monitor the treatment of diabetes.

No fasting is required. Patients should stop biotin consumption at least 72 hours prior to the collection.
