PLA2R autoantibodies, a multifaceted biomarker in nephrotic syndrome and membranous nephropathy.

ABSTRACT: The phospholipase A2 receptor antibody (PLA2R-Ab) test is a valuable first-line diagnostic tool for primary membranous nephropathy (MN), helping to identify PLA2R-related MN and potentially eliminating the need for a kidney biopsy in some individuals. By reducing the reliance on biopsies, the test streamlines diagnosis and improves patient care. However, determining the optimal PLA2R measurement method and cut-off is critical to maximizing the benefits of the test and minimizing any harms. A systematic review and meta-analysis were performed to evaluate serum- and urine-based biomarkers for distinguishing between PLA2R-related MN and non-PLA2R MN. Searches were conducted in databases including Medline, Embase, Cochrane Library, Scopus, Web of Science, International HTA Database and Clinica
