This simple and easy ELISA test detects glutamic acid decarboxylase (GAD) levels in human serum. It is particularly useful in early diagnosis of Insulin-Dependent Diabetes Mellitus (IDDM) or type1 diabetes in predisposed individuals several years before its clinical onset. IDDM is a worldwide health problem affecting 1-2% of the population and exacting a high cost in terms of morbidity and mortality, occurring most often in patients under 40 years of age.
