22319 Anti-Neutrophil Cytoplasmic Antibody (ANCA)

Anti-Neutrophil Cytoplasmic Antibody (ANCA)
Test Code: ANCA
Synonyms/Keywords
MPO, PR3, ANCA, Cytoplasmic Neutrophil antibody​
Test Components
P-ANCA, C-ANCA, Atypical ANCA, and Atypical C-ANCA​
Useful For
Anti-Neutrophil Cytoplasmic Antibodies are autoantibodies directed against cytoplasmic constituents of neutrophils and monocytes. The most common reasons for requesting an ANCA test are to diagnose and monitor inflammatory activity in the primary systemic small vessel vasculitides, namely Wegener’s Granulomatosis, Microscopic Polyangiitis (and its renal-limited form), Pauciimune Segmental Necrotizing Glomerulonephritis, and Churg-Strauss syndrome.​
