Clinical Significance
Phospholipase A2 Receptor (PLA2R) Antibody (Ab) testing provides physicians with a non-invasive tool for diagnosing primary membranous nephritis (PMN), an autoimmune disease most commonly mediated by autoantibodies to the podocyte antigen, PLA2R. PLA2R Ab is a highly specific biomarker for PMN and is detected in about 70-80% of patients. Moreover, PLA2R Ab levels frequently rise and fall with the clinical course of PMN and PLA2R Ab levels may have clinical utility in monitoring PMN patients for therapeutic response, remission, and disease relapse.
