is seen in 85% of patients with Wegener's granulomatosis, and evidence suggests that antibody titers correlate with disease activity and severity.
If a c-ANCA
returns strongly positive, the diagnosis of Wegener granulomatosis would seem to be more solidified and may indeed avoid a costly and dangerous biopsy.
The work-up should include a chest x-ray to rule out pulmonary infiltrates and laboratory testing to measure the ESR and levels of ANA, c-ANCA
, and rheumatoid factor.

While biopsy may not be required for confirmation of the diagnosis if the classic triad of upper airway, pulmonary, and renal disease is present and a test for c-ANCA
directed against PR3 is positive, in the majority of cases, biopsy is needed to confirm the diagnosis and begin therapy.
pattern shows granular cytoplasmic fluorescence, frequently accentuated between the nuclear lobes.
36) The staining of ANCA reaction with proteinase 3 will result in a cytoplasmic fluorescent pattern called c-ANCA
The p-ANCA and c-ANCA
tests are used to differentiate between various forms of vasculitis, an inflammation of the blood vessels, which results in a reduction of oxygen in the blood and damages vital organs in the body by restricting blood flow and damaging normal tissue.
