Description

Useful For: ZnT8 antibody is used to distinguish type 1 and type 2 diabetes mellitus, identify relatives of diabetic patients at most risk for developing diabetes, predict the future need for insulin treatment in adult-onset diabetic patients, and predict the future development of diabetes mellitus in women with gestational diabetes.

Negative results do not exclude the diagnosis of or future risk for type 1 diabetes mellitus. The risk of developing type 1 diabetes may be stratified further by testing for: 1) antibodies targeting insulin, IA2, and GAD65 and 2) HLA genetic markers. Careful monitoring of hyperglycemia is the mainstay of determining the requirement for insulin therapy.
