The three insulin antibodies mainly include islet cell antibody, insulin antibody and glutamic acid decarboxylase antibody, which are mainly used to identify and predict type 1 diabetes.
1. Islet cell antibody: the antigenic component of islet cell antibody is mainly islet cell cytoplasm, which is an organ-specific antibody. The detection of this antibody in the body indicates the damage of insulin β-cells, which is of diagnostic and predictive value for type 1 diabetes mellitus.
2. Insulin antibody: The appearance of insulin antibody can be divided into two cases, one is for diabetic patients who receive insulin treatment, and the other is for patients who do not receive insulin treatment. The presence of this antibody in patients who do not receive insulin therapy suggests the possibility of type 1 diabetes.
3. Glutamic acid decarboxylase antibody: This antibody targets glutamic acid decarboxylase enzyme in insulin β-cells, and the presence of this antibody suggests the possibility of type 1 diabetes.
Overall, the three insulin antibodies are mainly used to diagnose and predict type 1 diabetes mellitus, depending on the patient’s past history. A positive insulin antibody test is recommended for endocrinology consultation and standardized diagnosis and treatment under the guidance of a physician.
