Abstract:
The 1999 WHO classification delineates immune mediated type 1 diabetes from other types of diabetes by the presence of auto-antibodies against beta-cell constituents. The GAD65 auto-antibody test is the method of first choice because it has the highest sensitivity, specificity and positive predictive value and is the most standardized and well-characterized type 1 diabetes related auto-antibody analysis. It is recommended that demonstration of GAD auto-antibodies leads to diagnosis, classification or re-classification of diabetes patients as immune mediated type 1 diabetes.
