Appropriate Tests


Systemic necrotising vasculitis involving medium sized muscular arteries and associated with aneurysm formation.

The diagnosis is made on the basis of clinical assessment, diagnostic imaging procedures and/or biopsy of an appropriate site.

Creatinine, Electrolytes to assess extent of disease; C-Reactive protein or Erythrocyte sedimentation rate to assess activity of disease. Antineutrophil cytoplasmic Ab (ANCA) contribute to the clinical assessment in the differentiation of PAN from ANCA positive vasculitides - (eg microscopic polyangiitis and granulomatosis with polyangiitis) which have a broader range of vessels.
