About this test

This ANCA test uses immunofluorescence (IFA) to look for antibodies against neutrophils, a type of white cell. The pattern seen (C-ANCA or P-ANCA) helps diagnose vasculitis.

Why is this test done?

  • Screen for small-vessel vasculitis
  • Investigate kidney and lung problems together
  • Read with PR3 and MPO tests

Symptoms — when should you get tested?

  • Blood in urine
  • Cough with blood
  • Long-lasting sinus problems
  • Rash, fever and joint pain

Normal range

ANCA (IFA) Negative

Reference ranges differ slightly between labs, methods, age and sex. Always discuss your report with your doctor.

If your result is high

A positive result with a C-ANCA or P-ANCA pattern supports vasculitis, usually confirmed with PR3/MPO tests.

Common reasons
  • ANCA-associated vasculitis
  • Inflammatory bowel disease
  • Some drugs and infections
