CELl-DYN 3700血液分析仪复检规则制订及应用评价

目的建立CELL-DYN 3700血液分析仪复检规则,保证血细胞分析结果准确性,以利临床诊断和治疗。方法根据医院具体情况建立CELL-DYN 3700血液分析仪复检规则,并在规则指导下通过对1200份标本检测结果和显微镜镜检结果的数据分析,评价规则的可行性和可靠性。结果在规则控制下,有33.7%的标本需采用复检和复片措施以确保结果准确,虽依旧存在2.3%的假阴性,但已经低于国际标准化委员会血液专家制定的5%的最大允许范围。结论各临床实验室有必要根据自己所用仪器的特点制定出合理的血细胞复检和显微镜复片的规则,既保证每个血细胞分析结果的准确性,又减少不必要的工作负担。

Development of review criteria for CELL-DYN 3700 hematology analyzer and its evaluation

Objective To establish review criteria for accurate results on Abbott CELL DYN 3700 hematology analyzer.Methods Based on the rules of our laboratory,review criteria on CELL-DYN 3700 hematology analyzer were set up and 1 200 blood specimens were detected under the criteria.The automated results were compared with those detected by manual microscopic examination.All data were subjected to statistical analysis to find out the reliability of the rules.Results According to the criteria,33.7% specimens underwent blood reviews or smear reviews to ensure the accuracy,but still there existed 2.3% false negatives.Conclusions Each laboratory should develop its local criteria for blood cell counts and smear reviews based on the characteristics of the hematology analyzer,in order to ensure the veracity of results and reduce the workload.
