Laboratory tests may include CBC; serum electrolyte, blood urea nitrogen (BUN), and creatinine levels; erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels; and cardiac biomarker measurements, lactate dehydrogenase (LDH), and serum glutamic-oxaloacetic transaminase (SGOT; AST) levels. Serum titers for suspected infectious etiologies and testing for tuberculosis exposure (ie, PPD or interferon-gamma release assays) may be helpful.
