尿液分析仪质控量值范围研究

Study on value range of urine analyzer quality control

目的 :研究尿液分析仪的量值参考范围及其通用质控物的靶值方案。方法 :调研不同生产厂家尿液分析仪检测项目的量值参考范围,将实验室偏倚占比作为靶值方案的评价指标,分析2014年广西临床检验中心的室间质量评价原始数据。结果:p H、比重、胆红素、亚硝酸盐4项指标的靶值范围可靠,而白细胞、尿胆原、红细胞、酮体、葡萄糖、蛋白质6项指标的靶值范围需要改进。结论:室间质评的靶值及评价指标需要重新选定,才能达到尿检结果互认的标准。

Objective To study the reference range of the urine analyzer and the target value of the common quality control object. Methods The reference ranges of urine analyzer test items from different manufacturers were investigated, and laboratory bias proportion was used as an indicator of the evaluation of the target value scheme. EQA raw data of Guangxi clinical examination center in 2014 were analyzed. Results The target value ranges of p H, specific gravity, bilirubin and nitrite were found reliable, while the ones for WBC, URO, RBC, ketone body, glucose and protein needed improving.Conclusion The target values and evaluation indexes of EQA have to be reselected for mutual recognition of the results.
