Vasculitis in Adults Testing Algorithm

Testing for vasculitis in adults is indicated in patients with unexplained systemic illness with organ involvement in the upper airway, renal system, pulmonary system, dermatologic system, or neurologic system. An initial vasculitic workup assists in determining the organ systems involved and may include urinalysis, C-reactive protein, urea nitrogen/creatinine, CBC, ANCA and ANA testing, syphilis testing, and HIV testing.
