摘　　要：目的探讨血清降钙素原(PCT)在菌血症中的诊断价值。方法选取2019年1—6月吉林省白城市医院检验科收治的80例疑似菌血症患者为研究对象,根据抽签法分为对照组和观察组,各40例。对照组给予血液细菌培养,观察组给予血清PCT检测。以病理检测为金标准,比较两种检测方法的诊断效能。结果经病理检测,观察组与对照组各有38例患者确诊菌血症。观察组的诊断准确率为90.00%,高于对照组的70.00%,差异有统计学意义(P<0.05);两种检测方法的灵敏度、特异性、阳性预测值、阴性预测值比较,差异无统计学意义(P>0.05)。结论与血液细菌培养相比,血清PCT检测能够提高诊断准确性,在菌血症患者中具有较高的临床诊断价值。Objective To investigate the diagnostic value of serum procalcitonin(PCT)in bacteremia.Methods A total of 80 patients with suspected bacteremia admitted to the Clinical Laboratory of Baicheng City Hospital of Jilin Province from January to June 2019 were selected as the research objects,and they were divided into control group and observation group according to the method of lot,with 40 cases in each group.The control group was given blood bacterial culture,and the observation group was given serum PCT detection.The diagnostic efficacy of the two methods was compared with the gold standard of pathological detection.Results By pathological examination,38 patients in the observation group and the control group were diagnosed with bacteremia.The diagnostic accuracy of the observation group was 90.00%,which was higher than that of the control group(70.00%),the difference was statistically significant(P<0.05).There was no significant difference in sensitivity,specificity,positive predictive value and negative predictive value between the two detection methods(P>0.05).Conclusion Compared with blood bacterial culture,serum PCT detection can improve the diagnostic accuracy,and has higher clinical diagnostic value in patients with bacteremia.
