[The importance of beta-2 microglobulin determination in the urine in the detection of tubular proteinuria]. / Znacaj odredivanja beta-2 mikroglobulina u urinu u detekciji proteinurije tubulskog tipa.

ABSTRACT

In 38 patients with the positive finding of protein in the urine the determination of beta-2 microglobulin concentration was made in addition to the simultaneous determination of albumin, IgC and transfer in the urine and the calculation of differential protein clearance values for the identification of tubular proteinuria. Only 4 (10.53%) patients had proteinuria of tubular type, 16 patients had proteinuria of glomerular type, while proteinuria of the mixed glomerulo-tubular type was found in 18 (47.37%) patients. The safe separation of tubular proteinuria from that of glomerular type was made possible by the determination of beta-2 microglobulin concentration in the urine in the framework of detailed investigation.
