C反应蛋白联合白细胞计数及中性粒细胞百分率在感染中的诊断价值

The values of combined detection of C-reactive protein,white blood cell count and neutrophil ratio in infection

目的探讨C反应蛋白(CRP)、白细胞计数及中性粒细胞百分率的联合应用在感染中的诊断价值。方法回顾性调查已确诊有感染的患者158例,将其分成细菌性感染组和非细菌性感染组,检测患者静脉血中CRP浓度、白细胞计数和中性粒细胞百分率,并与对照组进行比较。结果细菌性感染组CRP浓度、白细胞计数和中性粒细胞百分率的检测值及异常率均明显高于非细菌性感染组及对照组(P<0.01);非细菌性感染组只有CRP浓度及其异常率高于对照组(P<0.05)。结论 CRP测定能补充白细胞计数和中性粒细胞百分率的不足,判断组织炎症或损伤的程度。CRP、白细胞计数和中性粒细胞百分率联合检测对感染的诊断更有临床意义。

Objective To evaluate the values of combined detection of C-reactive protein ,white blood cell count and neutrophil ratio in infection .Methods 158 patients diagnosed with infection were divided into bacterial infection group and non-bacterial infec-tion group .The concentrations of C-reactive protein ,white blood cell count and neutrophil ratio were detected ,which were compared with cases in the control group .Results The concentrations and abnormal rates of C-reactive protein ,white blood cell count ,neu-trophil ratio in bacterial infection group were significantly higher than those in non-bacterial infection group and control group（P〈0 .01） .The concentration and abnormal rate of C-reactive in non-bacterial infection group were significantly higher than those in control group（P〈0 .05） .Conclusion Determination of C-reactive protein can supplement the lack of white blood cell count and neutrophil ratio ,determine the degree of inflammation or injury .The combined detection of C-reactive protein ,white blood cell count and neutrophil ratio in infection has important clinical significance .
