Answer

A complete blood count (CBC) with differential may show an elevated white blood cell (WBC) count indicative of inflammation or invasive infection. The erythrocyte sedimentation rate (ESR) should be determined. An ESR higher than 120 mm/hr and a WBC count greater than 15,000/µL suggest osteomyelitis.
