Anti Neutrophil Cytoplasmic Antibodies (ANCA){pANCA and cANCA)

Testing for anti-neutrophil cytoplasmic antibodies (P-ANCA and C-ANCA) has been found to be useful in establishing the diagnosis of suspected vascular diseases (e.g., crescentic glomerulonephritis, microscopic polyarteritis and Churg-Strauss syndrome), bowel disease (Crohn’s Disease, ulcerative colitis, primary sclerosing cholangitis, and autoimmune hepatitis) as well as with other autoimmune diseases (drug-induced lupus, SLE, Felty’s syndrome).
