to investigate the determinants of the glomerular filtration of proteins in insulin-dependent diabetic patients we studied the fractional clearance of albumin ( theta alb ) and igg ( theta igg ) and the selectivity index ( si = igg clearance/alb clearance ) in 32 subjects with macroproteinuria ( albustix positive ) , in 29 subjects with microproteinuria ( albustix negative ) , and in 24 healthy control subjects .
