［摘要］目的探讨PCT、WBC和CRP对菌血症的辅助诊断价值。方 法 对202例患者进行血培养、PCT、WBC和CRP检测。根据血培养结果， 将患者分成阳性组与阴性组，然后对两组的PCT、WBC和CRP结果进行统 计分析。结果除PCT夕卜，两组的WBC、CRP比较，差异无统计学意义 (P>0. 05)o根据ROC曲线数据可知， ng/ml, 灵敏度为53. 5%,特异度为79. 8%。结论PCT对菌血症有辅助诊断价值。

［Abstract］ Objective To investigate the auxiliary diagnostic value of PCT, WBC and CRP for bacteremia. Methods 202 patients were given blood culture, PCT, WBC and CRP detection. According to the results of blood culture, the patients were divided into the positive group and the negative group, then PCT, WBC and CRP results of the two groups were statistically analyzed. Results Except for PCT, there was no statistical difference of WBC and CRP value in the two groups (P>0. 05) .According to the data of ROC curve, diagnostic critical value, sensitivity and specificity of PCT were ng/ml, % and %. Conclusion PCT is helpful for the diagnosis of bacteremia.
