The Anti Neutrophil Cytoplasmic Antibodies (PR3) – c-ANCA (Serum) test is used to detect the presence of antibodies that indicate autoimmune disorders, especially vasculitis. These antibodies play an important role in diagnosing conditions such as bacterial vasculitis and Churg-Strauss syndrome. Through this test, doctors can assess the patient’s health status and guide treatment based on the results, contributing to improved management of immune diseases. The sample is collected from the blood and analyzed in the laboratory.
