Methods: Collect the literature reports on the early diagnosis of respiratory tract infection in children by the combined detection of WBC, CRP and SAA in recent years, and follow up the relevant literature reports from the selection of ¡°new three routine¡± laboratory items for rapid diagnosis in pediatric outpatient department and the application of the combined detection of WBC, CRP and SAA in the early diagnosis of respiratory tract infection in children. Results: Many literature studies found that the combined detection of WBC, CRP and SAA has important clinical significance in the early diagnosis of respiratory tract infection in children. Conclusion: Through reviewing the relevant literature, we can understand the application of WBC, CRP and SAA combined detection in the early diagnosis of respiratory tract infection in children. To provide more accurate and reliable laboratory data for the early diagnosis and treatment of respiratory tract infection in children in the future. %K White Blood Cell Count %K C-Reactive Protein %K Amyloid Protein-A %K Children %K Respiratory Tract Infection %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=123277
