Anti-Neutrophil Cytoplasmic Antibodies (ANCA) IFA and MPO/PR3 Antibodies
|Stability:||Ambient: 8 Hour(s); Refrigerated: 2 Day(s); Frozen: 1 Month(s); Incubated: Unacceptable|
Positive results will be titered and reported next day.
|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).
