Use

Testing for anti‑neutrophil cytoplasmic antibodies (P‑ANCA and/or C‑ANCA) is useful in establishing the diagnosis of suspected vasculitic disorders such as crescentic glomerulonephritis, microscopic polyarteritis, and Churg‑Strauss syndrome, as well as associations with inflammatory bowel disease (Crohn’s disease, ulcerative colitis, primary sclerosing cholangitis), autoimmune hepatitis, drug‑induced lupus, systemic lupus erythematosus, and Felty’s syndrome.
