【摘要】 目的：探析血清降钙素原(PCT)联合血液细菌培养对菌血症的诊断价值。方法：选取2015年2月-2016年2月于本院接受诊治的25例菌血症患者与同期接受体检的25例健康者作为观察对象，将其分别纳入菌血症组与健康组。对两组观察对象均实施血清降钙素元与血液细菌培养检查，观察并分析其检测阳性率、治疗后PCT水平变化检测情况。结果：经检测后，菌血症组其PCT、血液细菌培养、两种方式联合检测的阳性率均明显高于健康组；菌血症组患者经治疗控制后PCT水平与治疗控制前相比差异均有统计学意义(P<0.05)。结论：血清降钙素原联合血液细菌培养在针对菌血症检测中可发挥较准确的诊断作用，可见其在临床上具备较高的应用价值。

    【Abstract】 Objective：To investigate the value of serum procalcitonin (PCT) combined with blood bacterial culture in the diagnostic of bacteremia.Method：25 patients with bacteremia and 25 healthy received health examination were selected as study subjects in our hospital fom February 2015 to February 2016.The serum levels of calcitonin and blood bacterial culture were examined in both groups.The positive rate and the level of PCT after treatment of two groups were observed and analyzed.Result：The positive rate of PCT and blood bacterial culture in the bacteremia group were significantly higher than that in the healthy group ......
