摘要
目的评价两种血清降钙素原定量检测系统性能，为实验室舍理选择降钙素原检测系统提供依据。方法参考美国临床实验室标准化委员会（NCCLS）文件EP9-A2收集血清标本测定批内精密度、线性、相关系数。结果检测系统A和检测系统B的低中高值测定结果的批内精密度分别为1．01％～4．44％和1．11％～8．77％之间；PCT测定结果相关系数为0．9977。结论两种检测系统降钙素原的检测结果具有较高的稳定性和相关性，但存在一定的偏差，临床实验室可根据需要选择不同的检测系统。
Objective To evaluate the performance of two kinds of quantitative testing system in detection of procalcitonin and provide the laboratory evidence to choice serum procalcitonin testing system for laboratory. Methods Collected serum sam- ples and determined within-run precision,linearity and relation using the National Committee for Clinical Laboratory Stand- ards （NCCLS） EP-A2. Results The within-run precision of detection system A and detection system B were in of 1.01 %- 4. 44% and 1.11% - 8.77 % ;Measuring results of related coefficient was 0. 997 7. Conclusion Test results two kinds of quantitative testing system of procalcitonin have high stability and correlation, but there was certain deviation. Clinical labo- ratory can choose according to need different detection system.
