There are variable data as to which proteins appear in abundance in the urine in various types of glomerular disease.
The attached abstract demonstrates one groups attempt at characterizing different types of glomerular disease by the protein type excreted. From the abstract:
Urinary protein electrophoresis (PEP) showed a well-selective pattern with albumin and beta globulin as the main constituents. In the other groups of proteinuric patients the hypoalbuminemia and hyper-alpha 2 globulinemia were milder and urinary PEP generally showed non-selective pattern.
