Exploration of Clinical Value of Detecting C-reactive Protein Level in Children with Acute Respiratory Infection

Objective: To explore the level of serum C-reactive protein (CRP) and clinical value in patients with acute respiratory infection (ARI) . Methods: The serum CRP level and the total and classifed count of white blood cell (WBC) were detected in 178 children with acute respiratory infection (infected group) and 50 healthy childred (control group). Results: The serum CRP level in infected group was significantly higher than that in control group ( P 0.01) , but there was no significant variation between 71 children infected by virus (from the infected group) and the controul group ( P 0.05) . If 8mg/L was used as critical-point for both, the positive rate was 100% in children infected by bacterium (107/107) , and 0% (0/71) in children! infected by virus. Conclusion: Detection of serum CRP level in the patients with acute respiratory infection may help to correct and sensitive establish the pathogen and to directly treat the disease.
