ANCA-MPO (ANTI MYELOPEROXIDASE ANTIBODIES), EIA

THIS TEST IS USED TO DETECT THE PRESENCE OF ANTI-MYELOPEROXIDASE ANTIBODIES (ANCA-MPO) IN YOUR BLOOD. THESE ANTIBODIES ARE PRODUCED BY THE IMMUNE SYSTEM AND CAN ATTACK HEALTHY TISSUES, LEADING TO INFLAMMATION AND DAMAGE. THE TEST IS USED TO DIAGNOSE AND MONITOR CERTAIN TYPES OF VASCULITIS, A GROUP OF DISEASES THAT CAUSE INFLAMMATION OF THE BLOOD VESSELS. ANCA-MPO IS A SPECIFIC TYPE OF ANCA THAT TARGETS THE PROTEIN MYELOPEROXIDASE, WHICH IS FOUND IN WHITE BLOOD CELLS CALLED NEUTROPHILS. ELEVATED LEVELS OF ANCA-MPO MAY INDICATE THE PRESENCE OF AN AUTOIMMUNE DISORDER SUCH AS GRANULOMATOSIS WITH POLYANGIITIS (FORMERLY KNOWN AS WEGENERS GRANULOMATOSIS) OR MICROSCOPIC POLYANGIITIS.
