摘　　要：目的分析使用血细胞分析仪检测血小板计数出现假性减少的原因及复查方法。方法根据该实验室复检标准,采用血小板出现假性减少的50例门诊或住院患者作为研究对象,分析假性减少的原因及其复查方法。结果 50例血小板假性减少样本中,42例为乙二胺四乙酸依赖性,3例为大血小板,2例白细胞周围卫星现象,3例冷凝集现象,对这些患者进行复查后可得到正常范围的血小板结果。结论 EDTA-PTCP患者经镜检涂片发现聚集现象,可用枸橼酸钠抗凝、无抗凝剂即刻上机、手工计数复查血小板数值以避免误诊。Objective To analyze the cause and reexamination method of pseudo-reduction of platelet by the blood cell analyzer. Methods 50 cases of patients with pseudo-reduction of platelet were selected as the research objects according to the reexamination standards, and the causes and reexamination method were analyzed. Results In the 50 cases of samples,Ethylenediaminetetraacetic acid – dependent occurre d to 42 cases, giant platelet occurred to 3 cases, and white blood cell satellite phenomenon occurred to 2 cases, and cold agglutination occurred to 3 cases, and the platelet results within the normal range could be obtained after reexamination. Conclusion The gather phenomenon is found in patients with EDTA-PTCP after the microscopy smear, and the platelet figure can be reexamined by the manual counting to avoid the misdiagnosis.
