MPO – ANCA ( P – ANCA )

The myeloperoxidase (MPO) antineutrophil cytoplasmic antibodies (ANCA) test detects the presence of MPO-ANCA, also known as p-ANCA, in the blood. This test is used to diagnose and monitor autoimmune vasculitis, such as microscopic polyangiitis and Churg-Strauss syndrome. A positive result indicates an autoimmune response against neutrophils, suggesting vasculitis. The MPO-ANCA test provides valuable information for diagnosing vasculitis, guiding treatment decisions, and monitoring disease activity. It helps ensure appropriate medical intervention and prevent complications associated with autoimmune vasculitis.
