Test ID: ANCA+

Test Name: Comprehensive Anti-Neutrophil Cytoplasmic Antibodies With MPO & PR3

Ordering Recommendation


Comprehensive panel for evaluating ANCA-associated vasculitis. First-line testing includes Myeloperoxidase (MPO) and Serine Proteinase 3 (PR3) antibodies. Indirect immunofluorescence (IFA) ANCA IgG by IFA may be used as an adjunct test when clinical suspicion persists despite negative MPO/PR3 results or when low antibody levels are suspected. For evaluation of autoimmune liver disease, use in conjunction with Autoimmune Liver Disease Panel

 

 

Note: As part of this panel, ELISA for MPO and PR3 antibodies will be performed, and ANCA IgG by indirect immunofluorescence (IFA) will also be performed concurrently, regardless of ELISA results.
