Antibody to the Mr 65,000 isoform of glutamic acid decarboxylase are detected in non-insulin-dependent diabetes in Japanese
It was recently reported that antibodies against glutamic acid decarboxylase (GADAb) have a high positive predictive value for insulin-dependency in non-insulin-dependent diabetic (NIDDM) patients. We studied 289 patients classified at onset as having NIDDM.
