[Indirect immunoelectrophoresis in the study of urinary proteins]

The indirect immunoelectrophoresis applied to the proteinurias is a simple and quick method, of usual execution, that makes use of not concentrated urines and discriminant between physiological and pathological proteinurias. The results obtained from a various casistic, collected in many years are presented. For the correlation which exist between morphological isototype and immunoelectropherogram, sometimes, it is possible to go up to the diagnosis of nephropathy also without applying to the renal biopsy.
