Insulin autoantibodies are antibodies produced by the immune system that mistakenly target and attack insulin or insulin-producing beta cells in the pancreas. Their presence is clinically significant as they are often associated with autoimmune forms of diabetes, particularly Type 1 diabetes, and can help differentiate it from Type 2 diabetes. A key association is that the presence of these autoantibodies can indicate a higher risk of developing diabetes in at-risk individuals, such as those with a family history of the disease.
