降钙素原(procalcitonin,PCT)以其高灵敏度、高诊断特异性以及持续稳定的特点作为脓毒症诊断指标之一[1-3],2009年JAMA文章报道基于PCT为指导可以减少抗生素使用[4]。目前PCT的临床检测方法主要有半定量胶体金比色法、电化学发光法和酶联免疫荧光法,此3种方法各有缺陷,均无法满足急诊科、重症监护室等对患者体征状况进行快速、及时的评价监测的需求。本研究将PCT与即时检验(point of care testing,POCT)的概念结合,建立一种上转发光免疫层析技术(up-converting phosphor technology based lateral flow assay,UPT-LF)快速定量检测PCT,并对其性能进行了系统评价,并以罗氏电化学发光法(Elecsys BRAHMS PCT)做为参比试剂进行了临床验证。
