摘　　要：目的探讨血细胞复检规则的重要性及血小板假性减少的原因及处理方法。方法通过工作中遇到的1例血小板假性减少的病例,根据血细胞分析复检规则,制作血细胞涂片显微镜复检及使用不同的抗凝剂处理检测血小板。结果血涂片镜检发现血小板聚集成堆,EDTA抗凝剂采血管检测血常规血小板异常减低,肝素抗凝管检测血常规血小板正常。结论复检规则在血常规检测中起着重要的作用。通过复检规则能避免单纯依靠仪器造成的误诊和漏诊,采用血涂片复检和更换肝素抗凝剂等方法可发现EDTA抗凝剂引起的血小板聚集,纠正由EDTA抗凝剂引起的血小板假性减少。Objective To investigate the importance of blood cell re examination rules and the causes and treatment of false reduction of platelets. Methods A case of thrombocytopenia was encountered in the work. According to the blood cell analysis re examination rules, blood smear microscopy was used to recheck and use diferent anticoagulants to detect platelets.Results Platelet aggregation was detected by blood smear microscopy. Routine blood routine test, blood platelet abnormality and blood routine examination of heparin anticoagulant tube were detected by EDTA anticoagulant. Conclusion The review rules play an important role in routine blood test. By reviewing the rules, he misdiagnosis and missed diagnosis can be avoided by relying solely on the instrument. Platelet aggregation induced by EDTA anticoagulant can be detected by blood smear reexamination and replacement of heparin anticoagulant. Correction of Pseudo thrombocytopenia by EDTA anticoagulants.
