探讨全自动血细胞分析仪计数血小板假性减低

Approach of False Decreasing in Platelet Count by Automated Blood Cell Counter

目的:探讨血细胞分析仪测定时造成血小板假性减少的因素,给临床诊断和治疗血小板减少症提供重要依据。方法:采用静脉血仪器法,末稍血稀释法,涂片镜检法,进行比较。结果:28份仪器测定结果血小板降低的标本中,26例采用不同的方法复查结果均正常,2例血小板减低,涂片镜检见巨大血小板。结论:仪器法测定血小板降低时,必须采用指尖血及涂片镜检进行复查,避免血小板假性减少的发生,为临床提供可靠的数据。

Objective：To discuss the reasons of false decreasing in platelet count by automated blood cell counter,to provide evidences on clinic diagnose and cure idiopathic thrombocytopenic purpura.Methods：Count the platelet by automated blood cell counter in vein blood and diluted fingertip blood and smear of blood check by microscope.Results：There are 26 results were normal by other methods among 28 platelet decreased samples,and 2 results were decreased accompany with big platelet.Conclusion：The diluted fingertip blood and smear of blood must be rechecked to avoid false decreasing of platelet count when the result of platelet count was decreased by automated blood cell counter.
