Anti-MPO Ab (RDL)
Use
Anti-MPO autoantibodies aid in assessment of certain autoimmune vasculitides such as microscopic polyarteritis and crescentic glomerulonephritis. MPO is the main target antigen of the antineutrophil cytoplasmic autoantibodies (ANCA) that give a perinuclear (pANCA) pattern on immunofluorescence.
