杭州地区29家医疗机构全血细胞计数准确度和一致性调查

目的了解杭州地区医疗机构全血细胞计数(complete blood count，CBC)项目检测结果的准确度和一致性，为全市医疗机构间该项目检测结果的互认提供基础。 方法用5份新鲜血标本对杭州地区29家代表性医疗机构进行CBC项目检测结果调查，标本同时送卫生部临床检验中心血细胞分析参考实验室定值。参照WS/T 406-2012中允许总误差要求及准确度验证方法，对回报结果进行准确度和可比性评价，及其合格率分析。 结果29家医疗机构回报了63台血液分析仪检测结果，WBC、RBC、Hb、HCT、PLT检测结果准确度验证合格率分别为100.0%、95.2%、98.4%、98.4%、100.0%；WBC、RBC、Hb、HCT、PLT、MCV、MCH、MCHC检测结果的可比性评价合格率分别为99.7%、94.9%、99.4%、100.0%、99.7%、99.7%、100.0%、100.0%。 结论杭州地区医疗机构的CBC项目检测结果准确度和一致性优良，该调查活动为开展检验结果互认积累了经验，且奠定了基础。

Survey on the accuracy and consistency of complete blood count in 29 medical institutions in Hangzhou

ObjectiveTo investigate the accuracy and consistency of complete blood count(CBC) in Hangzhou medical institutions in order to provide the foundation for mutual mutual recognition of the test results from different medical institutions in Hangzhou. MethodsFive fresh blood samples were used to investigate CBC in 29 representative medical institutions in Hangzhou. The samples were also sent to Hematology Reference Laboratory of National Center for Clinical Laboratories. The allowable total error requirement and accuracy verification method in WS/T 406-2012 were consulted. The accuracy and comparability of the return results were evaluated, the vatio of the results that meet the requirements were qualified. ResultsThe accuracy verification rate of the tests for WBC, RBC, Hb, HCT, PLT from the total of 63 hematology analyzers were 100.0%, 95.2%, 98.4%, 98.4%, and 100.0%. The qualified rate of the comparable evaluation of the test results for WBC, RBC, Hb, HCT, PLT, MCV, MCH and MCHC from the total of 63 hematology analyzers were 99.7%, 94.9%, 99.4%, 100.0%, 99.7%, 99.7%, 100.0%, and 100.0%. ConclusionsThe accuracy and consistency of CBC results are satisfied in the medical institutions in Hangzhou. This investigation has accumulated experience and foundation for the mutual recognition of test results.
