Abstract:
Objective To analyze National Center for Clinical Laboratories external quality assessment(EQA)of blood cell morphology,and to summarize the cell system,morphological types and frequency of EQA.Methods EXCEL software was used to analyze retrospectively 506 pictures from National Center for Clinical Laboratories 51 times EQA of blood cell morphology from 1999 to 2016,then the type and frequency were summarized.Results Among the 506 pictures in National Center for Clinical Laboratories EQA from 1999 to 2016,380 pictures came from peripheral blood,125 pictures came from bone marrow,and the ratio was 3:1.The remaining one came from cerebrospinal fluid cells.In results of 51 times EQA,there were 135 kinds of cell morphology,including 37.78% morphology once only.In blood cell types,mononuclear had the highest frequency(28 times),then atypical lymphocyte appeared 25 times.Conclusion It is necessary for each laboratory to learn the content of blood cell morphology,and master proficiently cell morphology characteristics,especially the basic cells in blood smear for the improvement of diagnosis accuracy.
