探究超敏C-反应蛋白（hs-CRP）联合血常规检测诊断小儿细菌感染性疾病的临床效果。

选择2014年8月至2015年2月于本院确诊的45例细菌感染性疾病患儿为观察组，同期45例健康儿童为对照组，两组患儿分别行hs-CRP检测、血常规检测及两者联合检测，比较两组患儿的检测指标采用三种检测方法诊断的符合率。

经检测，观察组患儿hs-CRP、白细胞数、中性粒细胞数分别为（13.75±8.52）mg/L、（11.02±4.31）× 10⁹/L、（7.52±2.65）× 10⁹/L均显著高于对照组患儿，差异具有统计学意义（t = 8.943、P = 0.000，t = 5.672、P = 0.006，t = 3.417、P = 0.011）；经hs-CRP联合血常规检测观察组患儿各项指标的阳性率显著高于hs-CRP、血常规单独检测，差异具有统计学意义（χ²= 12.114、P = 0.000，χ²= 3.814、P = 0.025）。

小儿细菌性感染性疾病经hs-CRP联合血常规检测诊断，可有效提高诊断符合率。

To investigate the clinical effects of high sensitivity C-reactive protein (hs-CRP) combined with routine blood test in diagnosis of bacterial infectious diseases in children.

Total of 45 children with bacterial infectious diseases in our hospital from August 2014 to February 2015 were collected as the observation group, and 45 cases of healthy children as control group. The children were treated by hs-CRP test, blood test and joint detection of both, the detection index of the two groups and three detection method in the diagnosis of coincidence rate in the observation group were compared, respectivly.

After detection, the levels of hs-CRP, white blood cell count, neutrophil count in the observation group were (13.75±8.52) mg/L, (11.02±4.31) × 10⁹/L and (7.52±2.65) × 10⁹/L respectively, which were significantly higher than those of control group, with significant differences (t = 8.943, P = 0.000; t = 5.672, P = 0.006; t = 3.417, P = 0.011). In addition, the positive rate of hs-CRP combined with routine blood test was significantly higher than that of the separate detection of hs-CRP or routine blood test, with significant differences (χ²= 12.114, P = 0.000; χ²= 3.814, P = 0.025).

The pediatric infectious disease diagnosis by hs-CRP combined with routine blood test, will improved the diagnosis rate effectively, which should be promoted in the clinical application.
