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):
86255

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.
