目的 分析探讨血常规与全血C反应蛋白(CRP)联合应用在儿科感染类型诊断中的价值。方法 选取我院2015年2 月-2016年2月收治的感染性疾病的患儿390例，其中经临床病理学诊断确诊为病毒感染患儿195例为病毒感染组； 经临床病理学诊断确诊为细菌感染患儿195例为细菌感染组。将所有患儿均进行血常规WBC计数和全血CRP测定并比 较。结果 细菌组患儿的CRP检测值明显高于病毒组患儿的检测值；病毒组感染性疾病患儿WBC阳性率(5.13%)明显低 于细菌组患儿的WBC阳性率(97.44%), 两组对比差异有统计学意义(P<0.05)。结论 血常规与全血CRP联合可有效诊 断儿科感染性疾病，指导临床合理用药，避免药物对儿童身体的危害，值得临床大力推广使用。

Objective To investigate the value of blood routine examination combined with CRP in the diagnosis of types of pediatric infections. Methods 195 cases with infectious diseases in our hospital from February 2015 to February 2016 were selected. 93 cases diagnosed as virus infection by clinical pathological diagnosis were seen as virus infection group. 102 cases diagnosed as bacterial infection by clinical pathological diagnosis were seen as bacterial infection group. All patients were given CBC WBC counts and CRP detection, then compare the CRP, WBC counts and positive rate of the two groups. Results CRP, WBC counts of the virus group were significantly lower than those of the bacterial group, CRP, WBC positive rates of the virus group (39.22%, 42.16%) were significantly lower than those of the bacterial group (93.55%, 83.87%), the difference was statistic significant (P<0.05). Conclusion Blood routine examination combined with CRP can effectively diagnose pediatric infectious diseases, guide clinical rational drug use, avoid the harm of drugs on children. It is worthy of clinic wide promotion.
