血小板检测结果异常时3种检测方法的比较和评估

摘要

目的:比较评估血小板检测结果异常时阻抗法、光学法和涂片镜检法3种检测方法的临床应用价值.方法:选取XE-2100全自动血细胞分析仪利用阻抗法进行的全血细胞分析中血小板报警信息提示结果可信度降低的样本,进行光学法血小板检测和涂片镜检法血小板复检,比较并分析这3种检测方法的结果.结果:大部分样本经过光学法复检可以纠正阻抗法可信度降低的结果,部分样本经过光学法依然不能纠正,主要原因在于检测结果没有满足仪器设定的纠正条件,需要涂片染色显微镜下核查血小板的数量.结论:当XE-2100全自动血细胞分析仪检测血小板结果异常时,需要用光学法纠正,若还是无法纠正,则需要手工推片染色镜检来确认.3种方法各有利弊,需互补使用.%Objective To compare the clinical values of impedance method,optical method and microscopy when used to detect platelet abnormal results.Methods Platelet re-examinations by optical method and microscopy were carried out in case of low confidence degree in platelet test with impedance method by XE-2100 automatic hematology analyzer,and then the results by the three methods were compared.Results Most of the low-confidence-degree results by impedance method could be corrected by re-examination by optical method,and the remained had to turn to microscopy due to unsatisfied requirements of the instrument.Conclusion Optical method has to be involved to correct the platelet abnormal results by XE2100 automatic hematology analyzer,and microscopy should be applied in case optical method doesn't work.The three methods gains advantages and disadvantages of themselves,and can be supplementaries for one another.
