The following proteins represent the different types of proteinuria: transferrin for “selective glomerular”; transferrin+IgG for “non-selective glomerular”; α1-microglobulin for “tubular”; α1-microglobulin+transferrin for “selective glomerular+tubular”; α1-microglobulin+transferrin+IgG for “non-selective glomerular+tubular”
