摘要:

［目的］ 探讨血细胞分析仪计数血小板误差原因及纠正方法。［方法］ 共收集血小板计数异常者96例，同时用全自动血细胞分析仪（包括阻抗法和流式细胞计数法）检测和目视显微镜计数法计数。［结果］ 采血不顺利、抗凝剂依赖、血小板体积偏大、小红细胞、乳糜血等均能引起血小板计数误差。［结论］ 用血细胞分析仪计数血小板时，遇到结果偏低或偏高，均要结合血小板直方图分布情况、仪器报警提示和血涂片镜检做出判断，对与实际病情不符的结果，要采取不同的方法进行修正。

Abstract:

［Objective］ To investigate the reason of platelet count error detected by blood cell analyzer and its rectified methods. ［Methods］ Ninety-six samples of abnormal platelet count were collected and detected by both automatic blood cell analyzer,including impedance method and flow cytometry method,and microscopic count. ［Results］ The following circumstances could result in platelet count error: unsuccessful hemospasia, dependence on anticoagulant, large platelet, microcyte and chylemia. ［Conclusion］ When platelet count is lower or higher than normal range, we should judge according to platelet histogram, abnormal report indication and microscopic examination of blood smear. It should be corrected by different methods if the result is not consistent with actual situation.
