Current classification divides MPGN into complement-mediated C3 glomerulopathy (C3G) and immune complex-mediated membranoproliferative glomerulonephritis (IC-MPGN) based on the immunofluorescence microscopy findings where C3 staining is minimum two-order magnitude stronger than any other immunoreactant in the case of C3G (2). Here, C3 is linked to primary membranoproliferative glomerulonephritis.
