<prompt> Which investigation should be done for diagnosis of idiopathic membranous glomerulopathy?Antibody to PLA2R on podocytesKidney biopsy with immunofluorescent stainingC3, C4 and CH50 levelsc-ANCA titers  <response>: Membranous Glomerulopathy associate with Malignancy The anti-PLA2R antibody Anti-phospholipase A2 Receptor antibody attaches to the phospholipase A2 receptor the antigen. The phospholipase A2 receptor is a protein found in the kidney filter glomerulus, specifically within a cell called the podocyte which makes up pa of this filter Diagnosed by- protein in the urine and kidney biopsy
