  • p-ANCA
  • c-ANCA
  • If c-ANCA or p-ANCA Screen is positive, a titer will be¬†performed at additional charge
  • If p-ANCA, c-ANCA or Atypical ANCA are positive, testing¬†will reflex to the following at an additional charge:
    • Myeloperoxidase Aby
    • Proteinase 3 Aby
  

ANCA (anti-neutrophil cytoplasmic antibodies) occur in patients with granulomatosis with polyangitis (GPA), microscopic polyarteritis, necrotizing or crescentic glomerulonephritis, other vasculitides and inflammatory bowel disorders (primarily ulcerative colitis).

Clinical and Interpretive info

  

p-ANCA: Negative

c-ANCA: Negative

  

If c-ANCA Screen is positive, c-ANCA titer will be performed at an additional cost. 

Screening performed at 1:20 dilution.
Titers performed for positive c-ANCA and p-ANCA at the following dilutions: 1:40, 80, 160, 320, 640, 1280. ANA will be performed at 1:20 on any Atypical p-ANCA to rule out interference. Note that ANA at this titer is utilized in the laboratory for interpretation only. It is not a reportable ANA result and should not be interpreted as a positive ANA for the diagnosis of lupus or other auto-immune disease.

Positive or atypical c-ANCA and p-ANCA will reflex to Myeloperoxidase Antibodies and Proteinase 3 Antibodies, IgG at an additional charge.
