Interpretive Data

Please see report for interpretive data.

Anti-Neutrophil Cytoplasmic Antibodies (ANCA) are generally found in the serum of patients with ANCA-associated vasculitis or other autoimmune disease.

Myeloperoxidase and Proteinase 3 Reference Ranges:
<21 Units Negative
21-30 Units Weak Positive
>30 Units Moderate to Strong Positive

ELISA method for ANCA correlates with Indirect Immunofluoresence as follows-
Myeloperoxidase = P-ANCA (Perinuclear Staining)
Proteinase 3 = C-ANCA (Cytoplasmic Staining)

ANCA performed using Indirect Immunofluorescent Assay (IFA).
