Objective:To investigate diagnosis value of combined detection of C-reactive protein ( CRP) and white blood cell ( WBC) in early infection of infants. Methods:Blood routine examination was conducted in 200 patients with respiratory tract infection and 98 age-matched healthy ones, and CRP was measured with Latex enhanced turbidimetric method. Results:The values of CRP and WBC in bacterial infection group were much higher than those in viral infection group and control group. Conclusions:It has a certain value to combined detection CRP and WBC in the early diagnosis of bacterial infection in infants.%目的：：探讨C-反应蛋白( CRP)与白细胞( WBC)联合检测在幼儿早期感染中的诊断价值。方法：对200例呼吸道感染者和98例同年龄阶段健康儿童进行血常规检测，并用胶乳增强比浊法测定CRP含量。结果：细菌感染组中CRP和WBC的测定值明显高于病毒感染组和对照组。结论：CRP和WBC联合检测对婴幼儿早期细菌感染的诊断有一定的价值。
