In this study we measured platelet size in blood smears using the Kontron Mop Videoplan (Kontron Electronic Group, Weesp, Holland). The blood smears were prepared at different times after phlebotomy; samples were collected in three different anticoagulants and 100 consecutive platelets were measured in each smear. A number of platelet parameters were determined, some of which were based on the log normal distribution of the platelet area. We found that the size of platelets in blood smears is also dependent on the time after phlebotomy and the anticoagulant used. This may be important for the comparison of platelet areas, a characteristic of various disorders. Our data indicate that the optimal interval after phlebotomy for preparation of blood smears is 2-5 min.
在本研究中，我们使用Kontron Mop Videoplan（荷兰韦斯普的Kontron电子集团）测量血涂片上的血小板大小。血涂片在静脉穿刺后的不同时间制备；样本采集于三种不同的抗凝剂中，每张涂片测量100个连续的血小板。测定了一些血小板参数，其中一些基于血小板面积的对数正态分布。我们发现，血涂片上血小板的大小也取决于静脉穿刺后的时间和所用的抗凝剂。这对于比较血小板面积可能很重要，血小板面积是各种疾病的一个特征。我们的数据表明，制备血涂片的最佳静脉穿刺后间隔时间为2 - 5分钟。
