ANCA-Associated Vasculitis Profile (ANCA/MPO/PR3)
Ordering Recommendation
Comprehensive panel for the evaluation of ANCA-associated vasculitis. For the preferred first-line panel, see Myeloperoxidase (MPO) Antibody and Serine Proteinase 3 (PR3) Antibody with Reflex to Anti-Neutrophil Cytoplasmic Antibody, IgG by IFA (3003746).
For evaluation of autoimmune liver disease, use in conjunction with Autoimmune Liver Disease Reflexive Panel (3002479).

Note
Specimens are screened for ANCA, MPO, and PR3. ANCA IFA is simultaneously tested on ethanol- and formalin-fixed slides to allow differentiation of C- and P-ANCA patterns.
