Overview
Laboratory Findings
- There are no specific lab tests for diagnosing polyarteritis nodosa.
- Diagnosis is generally based upon the physical examination and a few laboratory studies that help to confirm the diagnosis:
Electrolyte and Biomarker Studies
- CBC (may demonstrate an elevated white blood count)
- ESR (often elevated)
- Perinuclear pattern of antineutrophil cytoplasmic antibodies (p-ANCA) - not associated with "classic" polyarteritis nodosa, but is present in a form of the disease affecting smaller blood vessels, known as microscopic polyangiitis or leukocytoclastic angiitis.
- Elevated c reactive protein
