A preliminary study of C-reactive protein in the diagnosis and monitoring of Lyme disease.

Concentrations of C-reactive protein (CRP) in the serum of 14 patients suffering from Lyme disease were measured. 86% of these patients were found to have abnormally high concentrations of serum CRP (range 14-158 mg/L). The CRP concentration of a 60-year-old patient abated from 29 mg/L to 13 mg/L after treatment. Results suggest that serum CRP concentration can provide a valuable and accurate means for the clinical diagnosis and monitoring of Lyme disease.
