TEST DETAILS |
||
Reference interval: |
C-ANCA negative, P-ANCA negative. | |
Interpretation guide: |
A sample is considered negative if specific neutrophil staining is equivalent to or less than the negative control well. A sample is considered positive if cytoplasmic or perinuclear staining is observed. If suspicion for C-ANCA or P-ANCA, test progresses to PR3 or MPO, respectively, at an additional charge. | |
CPT code(s): |

Test includes: |
C-ANCA, P-ANCA antibody detection. | |
Methodology: |
Indirect Immunofluorescent Antibody (IFA) |
|
Synonyms: |
ANCA ANCA Battery Anti-neutrophil cytoplasmic antibody ANCAB
|
|
Clinical significance: |
The presence of anti-neutrophil antibodies (ANCA) can be used in conjunction with other tests and clinical findings to aid in the assessment of systemic vasculitis. ANCA has classically been divided into C-ANCA and P-ANCA depending on the immunofluorescence pattern observed. C-ANCA is suggestive of Wegener's granulomatosis and, to a lesser degree, microscopic polyarteritis, while P-ANCA has been associated with a more organ-limited vasculitis such as rapidly progressive glomerulonephritis. | |
