A three-phase evaluation of the Toa E-5000 Automated Hematology Analyzer was performed. The first phase consisted of evaluation of linearity, carryover, precisions, accuracy, sample stability, and effectiveness of the mixing and sampling mechanism. The second phase was comparison of erythroid and platelet parameters with results from a Coulter Counter Model S-Plus IV. The third phase consisted of comparison of the trimodal leukocyte differential count of the Toa E-5000 in 300 patients with four other differential methods. The first-phase studies showed excellent performance characteristics. Stability of samples at room temperature was good for a minimum of 12 hours, but storage for longer than 12 hours requires refrigeration to maintain stable values. The erythrocyte and platelet parameters showed good correlation with the Coulter S-Plus IV values except for the erythrocyte distribution width that is calculated differently. The third-phase studies are published elsewhere.
对东亚E - 5000全自动血液分析仪进行了三阶段评估。第一阶段包括评估线性、残留、精密度、准确性、样本稳定性以及混合和采样机制的有效性。第二阶段是将红系和血小板参数与库尔特S - Plus IV型血细胞计数器的结果进行比较。第三阶段是对300例患者东亚E - 5000的三分类白细胞差异计数与其他四种分类方法进行比较。第一阶段研究显示出优异的性能特征。样本在室温下至少12小时内稳定性良好，但储存超过12小时则需要冷藏以维持稳定值。红细胞和血小板参数与库尔特S - Plus IV型血细胞计数器的值显示出良好的相关性，但红细胞分布宽度的计算方法不同。第三阶段研究发表在其他地方。
