  • Serum parathyroid hormone (PTH) level

  • Coagulation factors - Prothrombin time, activated partial thromboplastin time, antithrombin III, protein C level, protein S level, anticardiolipin level, lupus anticoagulant level, factor V Leiden level, and homocysteine level

  • Cryoglobulin and rheumatoid factor measurements

  • Hepatitis C antibody level

  • Cryofibrinogen level

  • Serum amylase and lipase level

  • Aluminum level

  • Measures of inflammation - Erythrocyte sedimentation rate and C-reactive protein value

  • To exclude underlying vasculitis - Antineutrophilic antibody (ANA), antineutrophil cytoplasmic antibodies (ANCA)
