1·The number of hospital participating in Shanghai local IQC and EQA schemes increased year by year;

参加上海市地区性室内质量控制和室间质量评价的医院数量逐年增多；

2·Objective: to improve the quality of clinical laboratory results by external quality assessments (EQA).

目的：通过开展室间质量评价活动提高临床实验室检测质量。

3·Objective To discuss the validity of using external quality assessment (EQA) for the ALT measurement calibration.

目的探讨alt测定利用室间质评(EQA)作校准的有效性。

4·Objective To screen out and evaluate the dependability of the target value calculation method in the external quality assessment (EQA) of immunoglobulin.

目的通过对室间质量评价(EQA)靶值计算方法可靠性的评价，筛选应用于室间质量评价的靶值计算方法。

5·Conclusions Improvements in precision are still needed for many laboratory tests to assure the analytical quality required by the EQA total error criteria.

结论对于许多试验，为了保证满足室间质量评价要求的分析质量仍需提高其精密度水平。

6·Conclusion: the main reasons of the poor outcome are because of the poor equipment, low technical level, lax management, weak consciousness, and some staff pay more attention to EQA, but ignore IQC.

结论：许多中小实验室设备条件太差，整体技术水平不高，科室管理不严，质控意识薄弱或重室间质评、轻室内质控等，是造成这次考核成绩较差的原因。

7·Methods: The quality control samples of ESR were send to laboratories who participate the EQA program. The samples were determined by routine methods in Laboratory. The results were analyzed by NCCL.

方法：每年定期向参加红细胞沉降率室间质量评价活动的单位发放质评物，参加实验室用常规方法测定并回报结果，部临检中心对回报进行结果统计分析。
