Why This Biomarker Matters

Positive MPO antibodies indicate ANCA-associated vasculitis, a serious autoimmune disease. This test is crucial for diagnosing vasculitis affecting kidneys, lungs, and blood vessels.

Overview

This test detects antibodies against myeloperoxidase (MPO), an enzyme in certain white blood cells. Elevated MPO antibodies are associated with ANCA-associated vasculitis, a serious autoimmune disease that causes inflammation of blood vessels. MPO-ANCA is one form of this condition. Positive results help diagnose vasculitis and guide treatment with immunosuppressive therapies. This test is particularly important for patients with unexplained kidney disease, lung problems, or multi-system inflammation.
