Take control of your autoimmune and vascular health with Scan4Health’s ANCA Myeloperoxidase (P-ANCA) Test. This test is designed to detect anti-neutrophil cytoplasmic antibodies (ANCA) against myeloperoxidase (MPO), an essential marker for certain types of vasculitides and autoimmune diseases. With this targeted blood test, you can gain a better understanding of conditions like microscopic polyangiitis, Churg-Strauss syndrome (also called eosinophilic granulomatosis with polyangiitis), and other disorders that affect your blood vessels and immune system. Scan4Health combines expert knowledge, modern labs, and a focus on patient care to provide fast, reliable results and helpful guidance for your health.

• Routine: No fasting is required; you may maintain normal eating, hydration, and daily activities unless instructed otherwise.
• Medications: If you take immunosuppressants, antibiotics, steroids, or other drugs, share a complete list with your physician. Do not adjust or stop medicines unless directed by your doctor.
• Symptoms/History: Prepare a thorough outline of recent symptoms, including skin changes, unusual joint or muscle pain, coughing up blood, nosebleeds, rash, numbness, vision changes, or unexplained fatigue. Document any diagnoses or family history of vasculitis, autoimmune disease, inflammatory bowel disease, or chronic infections.
• Procedure Comfort: Wear clothing that allows easy access for a blood draw, typically from a vein in your arm.

This sophisticated blood test identifies autoantibodies directed against the myeloperoxidase enzyme in white blood cells. ANCA antibodies can mistakenly target the body’s own neutrophils, leading to inflammation and damage to blood vessels in various organs. P-ANCA (perinuclear pattern) targeting myeloperoxidase is seen in several diseases, most commonly microscopic polyangiitis (MPA), eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome), and, in some cases of glomerulonephritis, Goodpasture’s syndrome, and inflammatory bowel diseases such as ulcerative colitis. A blood sample is drawn, processed in the laboratory, and analyzed by immunoassay or ELISA methods that detect and quantify antibodies to MPO. When results are positive—especially in moderate or high titers—your physician considers the findings in the context of your symptoms, history, and other laboratory or imaging results. A negative test lowers the suspicion for ANCA-associated vasculitis but does not entirely rule it out, as these conditions can have fluctuating or atypical antibody profiles. The test is frequently ordered for patients with unexplained vascular symptoms, autoimmune inflammation, kidney problems, pulmonary hemorrhage, or chronic sinus issues. It can also assist in differentiating among types of vasculitides and in guiding follow-up of disease progression and treatment response.
