CRP and anemia: Initial testing was notable for an elevated C-reactive protein (CRP, 4.0 mg/dL; normal 0–1 mg/dL), markedly elevated erythrocyte sedimentation rate (ESR, 78 mm/hour; normal, 0–15 mm/hour), normocytic anemia (hemoglobin 11.6 g/dL; normal, 12.4–16.3 g/dL), and hypoalbuminemia (3.1 g/dL; normal, 3.6–5.1 g/dL).
