Diagnostic Approach to C3 Glomerulopathy (C3G) and Immune-Complex Membranoproliferative Glomerulonephritis (IC-MPGN)

Two one-page infographics outlining a stepwise, exclusion-based approach to confirming a diagnosis of C3 glomerulopathy (C3G) and primary immune-complex MPGN (IC-MPGN). Covers kidney biopsy findings, ruling out mimics (PIGN, MGRS, infectious and autoimmune causes), retinal drusen assessment, EM subtyping, and lab tests for complement dysregulation.
