摘要: 目的

了解上海地区各级各类医疗机构临床实验室红细胞(RBC)计数和白细胞(WBC)计数结果的一致性,为制定适宜的正确度验证计划提供指导。

方法

将2个批号弱固定处理新鲜全血样本按要求发放至全市710家临床实验室,并要求在3 d内完成检测,每批号样本重复检测5次,在收到所有上传结果后进行统计分析。

结果

使用12个品牌57个型号血液分析仪(包括WBC三分类和五分类仪器)的693家临床实验室回报了RBC、WBC结果;所有仪器2个批号RBC计数结果总变异系数(CV)分别为2.06%和1.99%,WBC计数结果总CV分别为4.72%和4.84%;不同仪器组2个批号RBC计数结果的CV为0.76%~3.18%,WBC计数结果的CV为1.73%~6.32%,其均值均在各自总均值的95%可信区间内。

结论

上海地区临床实验室RBC、WBC结果具有较好一致性;弱固定处理新鲜全血样本可替代新鲜全血用于正确度验证计划。

Abstract: Objective

To study the consistency of red blood cell (RBC) and white blood cell (WBC) counts in Shanghai, and to provide the reference for the appropriate accuracy verification project.

Methods

A total of 2 batches of weak-fixation-treatment whole blood samples were delivered to 710 clinical laboratories in Shanghai. Every laboratory was required to finish the determination within 3 d, with 5 duplicated determination results for each batch. All the determination data were uploaded via internet for statistical analysis within scheduled time.

Results

A total of 693 clinical laboratories, with hematology analyzers (three- and five-classification instruments) spanning 12 brands and 57 models, reported their data of RBC and WBC counts. The coefficient of variation (CV) for RBC of 2 batch samples were 2.06% and 1.99%, respectively. The CV for WBC of 2 batch samples were 4.72% and 4.84%, respectively. The CV of different analyzers for RBC and WBC of 2 batch samples were 0.76%-3.18% and 1.73%-6.32%, respectively, and the means were within 95% confidence interval.

Conclusions

The counting results of RBC and WBC in the clinical laboratories in Shanghai have consistency, and fresh weak-fixation-treatment whole blood sample is acceptable for substituting fresh whole blood in the application of the accuracy verification project for RBC and WBC counts.
