The immulogical diagnoses value of the combined detection islet autoantibody diabetes among adult diabetes

Objective To explore the clinical value of the investigation of three islet autoantibody in newly diagnosed adult patients with DM.Methods To randomly select 786 patients newly diagnosed DM and detected GAD-Ab、ICA、IA-2A by ELISA,compared the positive rate of difference between single and combined detection.Results The positive rates of GAD-Ab、ICA、IA-2A of these patients were 18.2%,10.5% and 17.9%,respectively.The positive rate of combined detection with GAD-Ab、ICA and IA-2A was significantly higher than that of single detection.And the positive rate of combined detection in 20~45 years old group was significant higher that of 46~65 years old group patients.Conclusion The combination detection of islet autoantibody can increase the diagnose rate of adult diabetes in newly diagnosed patients with diabetes.The positive rate islet autoantibody in 20~45 years old group was higher than that in 46~65 years old group.
