摘要 目的比较血清降钙素原(PCT)与血液细菌培养在菌血症患者诊断中的应用价值。方法对122例临床怀疑菌血症患者采用双抗免疫夹心化学发光法检测其PCT水平,同时进行血液细菌培养。根据血液细菌培养结果,按照培养时间分组,分别统计每组的平均PCT值,然后比较各组PCT值的差异性。结果血液细菌培养报阳时间能反应患者血液中的含菌量,血培养第1~2天阳性组PCT平均含量为(16.29±4.20)μg/L,第3~4天阳性组PCT平均含量为(9.44±2.70)μg/L,第5天后阳性组PCT平均含量为(1.50±0.85)μg/L,血培养阴性组PCT平均含量为(0.30±0.51)μg/L,各研究组相比,差异均具有统计学意义(P<0.01)。结论在菌血症患者中PCT检测结果与血培养结果是一致的,PCT升高的水平及其动态变化与疾病的严重程度及愈后有关,PCT能及时反映临床过程,PCT检测的便利、快速、动态监测要优于血培养。
