C-ANCA

C-ANCA

C-ANCA (Cytoplasmic Anti-Neutrophil Cytoplasmic Antibody) is a blood test used to help evaluate certain autoimmune conditions, particularly vasculitis such as granulomatosis with polyangiitis. It may be recommended when symptoms involve the respiratory system, kidneys, or unexplained inflammation. A positive result can provide supportive information but does not confirm a diagnosis on its own. Results should be interpreted along with symptoms and other clinical findings.
