[Qualitative study of proteinuria in diabetic nephropathy]. / Estudio cualitativo de la proteinuria en la nefropatía diabética.

The qualitative features of the proteinuria in diabetic nephropathy was studied by carrying out tests of clearance quotient of IgG and albumin in diabetic patients. Diabetic patients with micro and macroalbuminuria showed a major selectivity of proteinuria in relation to normoalbuminuric patients; this suggests a loss of anions at glomerular level.
