脑脊液神经元性烯醇化酶生物参考区间的建立

摘要

目的：建立适合本实验室的脑脊液神经元特异性烯醇化酶（NSE）生物参考区间。方法参照美国临床实验室标准化委员会（NCCLS）C28‐A2文件推荐的方法，收集120例无神经系统疾病的个体建立脑脊液NSE生物参考区间，并参照中国合格评定国家认可委员会CL38：2012文件的要求对生物参考区间进行评审。结果建立的脑脊液NSE生物参考区间为0～3．14 ng／mL。脑脊液NSE浓度与年龄、性别无明显相关性（P＞0．05）。结论采用上述方法建立生物参考区间可靠、准确、科学、实用，符合临床要求，值得推广应用。%Objective To establish the reference intervals of neuron specific enolase (NSE) in tumor markers in cerebrospinal fluid .Methods According to National Committee for Clinical Laboratory Standards document C 28‐A2 ,120 samples were collected to establish reference intervals .Then ,the established intervals were evaluated according to China National Accreditation Service for Conformity Assessment document CL38 :2012 .Results The biological reference interval of NSE in cerebrospinal fluid was 0-3 .14 ng/mL .There was no significant correlation between cerebrospinal fluid NSE level and age ,sex (P> 0 .05) .Conclusion Method used in this study could be ensured reliable ,accurate ,scientific and practical ,desirable for clinical requirement and with great poten‐tial for clinical application .
