Overview
Laboratory Findings
Basic lab tests may include a
- CBC - leukocytosis, eosinophilia > 10%
- Chem-7 (look for creatinine) - Elevated serum BUN (> 40 mg/dL) or serum creatinine (> 1.5 mg/dL)
- Muscle enzyme
- Liver function tests
- ESR - elevated ESR ≥ 50 mm/hour Westergren in temporal arteritis
- Hepatitis seroloties
- Urinalysis - microscopic hematuria or RBC casts in Wegener's granulomatosis
Additional, more specific tests include:
- Antinuclear antibody (ANA) test can detect an underlying connective tissue disorder, especially SLE
- Complement levels that are low can suggest mixed cryoglobulinemia, hepatitis C infection, and SLE, but not most other vasculitides.
- Antineutrophil cytoplasmic antibody (ANCA) may highly suggest Wegener's granulomatosis, microscopic polyangiitis, Churg-Strauss syndrome, or drug-induced vasculitis, but is not diagnostic.
