FIG. 5.
IAA levels from MSD-IAA assay and our current radioassay (mIAA) were compared among 100 newly diagnosed patients with type 1 diabetes (A), 70 prediabetic patients (B), and 50 blinded DASP workshop patient samples (C). The two assays were correlated (P < 0.0001), but MSD-IAA assay had higher sensitivity for all 3 groups with both assays set at 99% specificity.
