Anti-MPO AntibodiespANCA-specific AntibodyFor diagnosis and monitoring inflammatory activity in primary systemic small vessel vasculitides. The anti-MPO-ANCA EIA is useful for confirming positive ANCA results by IFA, particularly with the pANCA pattern. Presence of anti-MPO antibodies is highly specific for idiopathic and vasculitis-associated crescentic glomerulonephritis, classic polyarteritis nodosa, Churg-Strauss syndrome, and polyangiitis overlap syndrome without renal involvement. Levels of anti-MPO are elevated during active phases of disease and lower during remission. Therefore, monitoring anti-MPO levels can aid in disease management.
