目的:评估PCT预测血流感染和血培养菌种的临床价值。方法:分析比较2013年1-12月间的3343例血培养结果和同时测定的PCT结果。结果:331例血流感染患者的PCT浓度显著高于2856例非血流感染者的浓度,两者的PCT中位值为3.2ng/ml对0.4ng/ml( P<0.05)。PCT鉴别两者的ROC曲线下面积(AUC)为0.86,敏感性与特异性分别为0.76和0.86.结论:PCT有助于血流感染的正确诊断和血培养污染的排除。

Objective]Procalcitonin(PCT) was evaluated as a parameter for predicting bacteremia diagnosed by blood cultures . [Methed]Blood cultures and PCT levels from 3343 specimens collected in 2013were analyzed [Result]The PCT concentrations of bacteremia cases(n=331) were significantly higher than those of non-bacteremia(n=2856)(median:3 .2ng/ml vs 0 .4ng/ml ,P<0 .05 ) .The area under the receiver operating characteristic curve (ROC-AUC ) of PCT for discriminating bacteremia from non-bacteremia was 0 .86 ,and sensivityorspecialitywas 0 .76 or 0 .86 .[Conclusion]PCT could be helpful in the accurate diagnosis of bacteremia .
