The technique of collecting blood samples is primarily responsible for the appearance of platelet-agglomeration in cats. Blood obtained by the conventional way ("one syringe technology", drips of blood) caused in 52% of the cases an activation of the large and therefore active thrombocytes however. Rejection of the first 2-5 ml blood for the platelet count ("two syringe technology") reduced the rate of platelet-agglomeration significantly. No big differences in platelet-agglomeration were found with regard to the place used for collecting blood (V. cephalica antebrachii/V. jugularis). Platelet-agglutination was observed with Li-Heparin, K-EDTA, Na-Citrat or ACD anticoagulated blood samples. Citrat (Na-Citrat, ACD) seemed to have a stabilizing effect on feline thrombocytes as has been described for human thrombocytes. The platelet count in cats should be performed within 30 minutes.
采血技术是导致猫出现血小板聚集的主要原因。然而，采用传统方式（“单注射器技术”，滴血法）采集的血液，在52%的病例中会激活大型且因此活跃的血小板。在进行血小板计数时舍弃最初的2 - 5毫升血液（“双注射器技术”）可显著降低血小板聚集率。在采血部位（前臂头静脉/颈静脉）方面，未发现血小板聚集有显著差异。在使用锂肝素、钾乙二胺四乙酸、柠檬酸钠或酸性枸橼酸盐葡萄糖抗凝的血液样本中均观察到了血小板凝集现象。柠檬酸盐（柠檬酸钠、酸性枸橼酸盐葡萄糖）似乎对猫的血小板有稳定作用，这与人类血小板的情况类似。猫的血小板计数应在30分钟内完成。
