Phospholipase A2 Receptor

PLA2R Antibody testing is peformed by a referral laboratory. This assay is only available to members of Oxford University Hospitals NHS Foundation Trust.

The Phosphlipase A2 receptor (PLA2R) was recently discovered as a target autoantigen in patients with idiopathic membranous nephropathy (IMN). Autoantibodies directed to PLA2R were found in 52-82% of individuals with IMN but only to a small percentage (5-25%) in sera from patients with secondary MN. Since anti-PLA2R are strongly associated with disease activity, it is thought they are pathogenic, but no clear mechanisms of pathogenesis for IMN have so far been identified.

This assay is performed at a referral laboratory (external users requiring serum PLA2R antibody levels are advised to contact the referral laboratory directly):
