This indicator helps diagnose Wegener’s granulomatosis and allows differentiation between primary biliary cirrhosis and sclerosing cholangitis. This indicator is also useful in differentiating ulcerative colitis. The investigation of Wegener’s granulomatosis involves identifying a specific triad: granulomatous inflammation of the respiratory tract, vasculitis, and glomerulonephritis. The ANCA test result can be presented in three possible variants: 1) negative reaction; 2) cytoplasmic type reaction – c-ANCA; 3) perinuclear type reaction – p-ANCA.
