CRP and infection: The total leucocyte count (TLC = 6500/μL, normal range: 4000-10,000 μL), C-reactive protein (CRP = 6.55 mg/dL, normal < 5.0 mg/dL), and erythrocyte sedimentation rate (ESR = 22 mm/hr, normal up to 30 mm/hr in females over 50 years of age) were all within near-normal limits, showing no significant signs of infection.
