The summarized data and other studies to date indicate that performance of the Pentra 60 is comparable to other hematology analyzers for all CBC and 5-Diff parameters. Comparative studies indicate good correlation for all the reportable CBC parameters, lymphocyte counts, and neutrophil counts with 24 hr stability on blood samples. Good intermethod correlations on monocyte and eosinophil counts were observed. Only basophil counts showed poor intermethod correlations, but this is expected on a statistical basis, and the counts are similar to those reported for other hematology analyzer performance studies. The combination of the MDSS and stepper motor fluidic system allows for low-volume blood sampling, compact size, and low operational noise level. The Pentra 60 is well suited for physician's office laboratories, medical clinics, small- or medium-size hospitals with less than 100 CBCs per day, and larger hospitals or reference laboratories that need back-up for a high-end automated hematology analyzer.
汇总数据及迄今为止的其他研究表明，对于所有全血细胞计数（CBC）和五分类（5-Diff）参数，Pentra 60的性能与其他血液分析仪相当。比较研究表明，所有可报告的CBC参数、淋巴细胞计数和中性粒细胞计数具有良好的相关性，血液样本在24小时内保持稳定。单核细胞和嗜酸性粒细胞计数的方法间相关性良好。仅嗜碱性粒细胞计数的方法间相关性较差，但从统计学角度来看这是预期的，且该计数与其他血液分析仪性能研究报告的结果相似。MDSS和步进电机流体系统的结合实现了低体积血液采样、紧凑的尺寸以及低运行噪音水平。Pentra 60非常适合医生办公室实验室、医疗诊所、每日CBC检测量少于100例的中小型医院，以及需要高端自动血液分析仪备用设备的大型医院或参考实验室。
