目的:总结过去10年参加血细胞形态学EQA的经验与不足,以求改进提高。方法:对2007~2016年参加的全国血细胞形态学EQA结果进行统计回顾性分析。结果:在295幅有效血细胞质评图片中,全国参评实验室平均符合率86.9%,本院符合率90.2%,本院骨髓细胞比末梢血细胞错报率高7.5个百分数,出现频率最高的是异型淋巴细胞18次。结论:参加血细胞形态EQA提高了检验人员血细胞识别能力,有效保证了血细胞形态学检验质量。
OBJECTIVE: To summarize the experience and shortcomings of participating in blood cell morphology EQA in the past 10 years in order to improve and improve. Methods: The National Blood Cell Morphology EQA results from 2007 to 2016 were statistically analyzed retrospectively. Results: In the 295 pictures of cytoplasm quality assessment, the average accreditation laboratory in China was 86.9% and the hospital compliance rate was 90.2%. The misdiagnosis rate of myeloid cells in peripheral blood was 7.5% higher than that in peripheral blood cells. The frequency of abnormal appearance was the highest Lymphocytes 18 times. Conclusion: Participating in blood cell morphology EQA improves the blood cell recognition ability of the examiner and effectively guarantees the quality of blood cell morphology test.
