Application of C-reactive Protein Test in Acute Respiratory Infection of Children

Objective: To study the differentiation and treatment effect estimated value of c-reactive protein (CRP) test in acute respiratory infection of children. Methods: The CRP value in serum of respiratory infection group and control group (normal children) was examined respectively from Jan 2004, to Dec, 2007. Results: (1) The serum CRP positive rate in acute respiratory infection group was much higher than those in control group and had significant differentiation (P0.01). (2) The CRP value reduced rapidly in recovery phase of disease. Conclusion: The serum CRP test has important value in differentiating bacteria or virus infection and estimating disease change or treatment effect in acute respiratory infection of children.
