Predictive value of combined determination of ICA、64KDAb and IAA in the first-degree relatives of type I diabetics / 中国糖尿病杂志

ABSTRACT

Objective　To study the predictive value of islet cell antibody (ICA),64KD protein antibody(64KDAb) and insulin auto-antibody (IAA) in the first-degree relatives of type 1 diabetics.Methods　The determination of islet autoantibody distribution in type 1 diabetes patients,first-degree relatives without diabetes and normal individuals was made.Results　The results revealed that ICA and 64KDAb positive rate in type I diabetes patients and their first-degree relatives was significantly higher than normal individuals.The positive rate of 64KDAb is higher than that of ICA and IAA. Conclusion　These results suggest that 64KDAb's sensitivity is higher than ICA and IAA's,so 64KDAb is more valuable as the marker of predicting type 1 diabetes.The combined determination of ICA,64KDAb and IAA might improve the value for predicting diabetes.
