  2. Indications
    1. Small Vessel Vasculitis
    2. Wegener's Granulomatosis suspected (cANCA)
  3. Mechanism
    1. Antibodies bind to cytoplasmic region of Neutrophils
  4. Labs
    1. Cytospin preparations of Neutrophils are permeabilized
    2. Binding of serum antibodies assessed as with ANA

Antineutrophil Cytoplasmic Antibodies (C0103647)

Definition (MSH) Autoantibodies directed against cytoplasmic constituents of POLYMORPHONUCLEAR LEUKOCYTES and/or MONOCYTES. They are used as specific markers for GRANULOMATOSIS WITH POLYANGIITIS and other diseases, though their pathophysiological role is not clear. ANCA are routinely detected by indirect immunofluorescence with three different patterns: c-ANCA (cytoplasmic), p-ANCA (perinuclear), and atypical ANCA.
