MPO (P-ANCA) Ab IgG

MPO (Myeloperoxidase) P-ANCA Ab IgG is a blood test used to detect antibodies against myeloperoxidase, an enzyme found in white blood cells. This test helps diagnose autoimmune diseases, particularly vasculitis, which causes inflammation of blood vessels. It is commonly used to evaluate conditions like microscopic polyangiitis (MPA) and other autoimmune disorders affecting the kidneys, lungs, and small blood vessels.

The presence of MPO antibodies indicates an immune system attack on the body’s own tissues, leading to inflammation and potential organ damage. This test is often recommended for individuals experiencing symptoms like unexplained fatigue, fever, joint pain, skin rashes, kidney issues, or respiratory problems.

A simple blood sample is required, and fasting is not necessary. The results help doctors determine the presence of autoimmune vasculitis and guide treatment plans. If MPO antibodies are detected, additional tests and clinical evaluation may be needed to confirm the diagnosis.

This test is suitable for all age groups but is particularly recommended for individuals with suspected autoimmune diseases or unexplained systemic inflammation. Since autoimmune conditions can be complex, consulting a doctor is essential for accurate diagnosis and appropriate management, which may include immunosuppressive therapy or other targeted treatments.
