摘要

新的创新平台的发布帮助了即时检测市场的增长,并巩固了其在各种临床环境中的广泛应用。由于引入了通常以远离实验室的诊所为中心的新型患者途径,对实验室级参数和护理点分析仪结果的需求现在至关重要。在本文中,我们比较了HORIBA医疗公司的主流血液分析仪Pentra 120和最近发布的Yumizen H500点护理分析仪提供的5组分白细胞(WBC)差异。Yumizen H500基于HORIBA的Micros平台,目标是护理点/初级保健市场。Yumizen H500能够在大约2分钟内测量全血计数(27个参数),包括5部分白细胞差异,仅使用20 μ L全血。该分析仪还具有开放和封闭静脉管选项,使其适用于儿科和毛细管样品,以及更容易和更安全的使用在护理点设置。我们发现所有全血细胞计数参数都是可重复的,并且与之前的精确研究相比很好;同样,中性粒细胞、淋巴细胞、单核细胞和嗜酸性粒细胞的患者R2值也比较好,白细胞为0.994,中性粒细胞为0.952,淋巴细胞为0.942,单核细胞为0.84,嗜酸性粒细胞为0.81。总之,与我们研究所的主流实验室分析仪相比,Yumizen H500提供了可重复、精确和准确的结果。

A Comparison Between the HORIBA Yumizen H500 Point-of-Care Hematology Analyzer With a 5-Part White Cell Differential and the HORIBA Pentra 120
Abstract The release of new and innovative platforms has helped the point-of-care testing market to grow and cement its wider uptake in various clinical settings. Driven by the introduction of novel patient pathways often centered on clinics remote from a laboratory, the need for laboratory grade parameters and results from point-of-care analyzers is now critical. In this paper, we compare the 5-part white blood cell (WBC) differential from HORIBA Medicals mainline hematology analyzer, the Pentra 120, and those provided from the recently released Yumizen H500 point-of-care analyzer. The Yumizen H500 is based on HORIBA's Micros platform and is aimed at the point-of-care/primary care market. The Yumizen H500 is capable of measuring a full blood count (27 parameters) including a 5-part WBC differential using only 20 &mgr;L of whole blood in approximately 2 minutes. The analyzer also has both open and closed venous tube options, making it suitable for pediatric and capillary samples as well as easier and safer to use in the point-of-care setting. We found that all full blood count parameters were intra-assay reproducible and compared well with previous precision studies; likewise, the patient R2 values for neutrophils, lymphocytes, monocytes, and eosinophils also compared well at 0.994 for WBC, 0.952 for neutrophils, 0.942 for lymphocytes, 0.84 for monocytes, and 0.81 for eosinophils. In conclusion, the Yumizen H500 provides reproducible, precise, and accurate results compared with our institute's mainline laboratory analyzers.
