SUIT, secretory units of islets in transplantation: An index for therapeutic management of islet transplanted patients and its application to type 2 diabetes.

Abstract Evaluation of a patient's pancreatic β-cell function is important in both diagnosis and treatment of diabetes. We sought to determine β-cell function with a single sampling of blood. Examination of fasting blood glucose (F-BG, mM) and C-peptide (F-CPR, nM) levels in seven post-islet-transplanted states of four patients revealed a linear relationship between F-BG and F-CPR. Assuming that normal subjects aged R 2  = 0.68, P R 2  = 0.34, P
