摘要:

目的 评估某品牌7种微小RNA(miRNA)检测试剂盒的检测性能。方法 采用多中心横向联合评价方法,在全国范围内选择10家检测中心在同一时间使用同一批样本,对同一批号试剂进行性能评估。检测项目为miR-21、miR-26a、miR-27a、miR-122、miR-192、miR-223和miR-801,以miR-1228为内参。评估参数包括精密度、符合率、检出限和抗干扰能力。结果 10家检测中心检测8种miRNA的循环阀值(Ct)的批内变异系数(CV)均<5.00%,批间CV均<6.50%。10家检测中心检测20例临床血浆样本的总符合率均为100.00%(20/20),对50拷贝/μL标准参考品的检出率均为100.00%(20/20)。血红蛋白200 g/L、胆红素1 000 μmol/L和三酰甘油100 mmol/L对检测结果无明显干扰。结论 该试剂盒检测7种miRNA的精密度、符合率、检出限和抗干扰能力表现良好,可满足不同地区、不同实验室和不同检测系统的使用需求和预期用途,具有一定的临床应用价值。

Abstract:

Objective To evaluate the determination performance of a 7-microRNA(miRNA) test kit. Methods A total of 10 laboratory centers used the same samples to evaluate the performance of the same batch of reagents during the same period through multicenter evaluation. The determination objects were miR-21,miR-26a,miR-27a,miR-122,miR-192,miR-223 and miR-801,with miR-1228 as the internal reference.The evaluation parameters included precision,consistency,determination limit and anti-interference capability. Results The intra-batch coefficient of variation(CV) and inter-batch CV of cycle threshold(Ct) values of the 10 laboratory centers for 8 miRNA were all <5.00% and <6.50%,respectively. The total consistency of 20 clinical plasma samples determined by the 10 laboratory centers was 100.00%(20/20). The determination rate of 50 copies/μL standard reference materials determined by the 10 laboratory centers was 100.00%(20/20). The interfering substances with the final concentration of 200 g/L hemoglobin,1 000 μmol/L bilirubin and 100 mmol/L triglyceride had no interference on the determination results. Conclusions The precision,consistency,determination limit and anti-interference capability of this kit are good,which can meet the different needs of regions,laboratories and determination systems. It has certain clinical application value.
