The global healthcare landscape is experiencing increasing demand for CLIA-waived testing facilities that offer diagnostic capabilities at lower costs and greater convenience than traditional laboratory testing. While several new diagnostic tools have emerged to fulfill testing requirements in these environments, centrifuges have been stymied from transitioning to the point-of-need as the US Food and Drug Administration (FDA) classifies them as mostly unsuitable for use in CLIA-waived environments. Limitations in sample processing capabilities adversely affects the ability for CLIA-waived testing environments to offer a broad testing portfolio and present-day diagnostics are bottlenecked by the requirement for centrifugation. Here we present the High Efficiency Rapid Magnetic Erythrocyte Separator (H.E.R.M.E.S), a rapid low-cost technology that can perform the separation of red blood cells from plasma at a fraction of the time and cost of that of a centrifuge. We demonstrate that H.E.R.M.E.S is able to obtain highly-pure plasma (greater than 99.9% purity) at less than 2 minutes per test. Further, we detail that it is an easy-to-use method capable of being incorporated with present-day diagnostic technologies and prove that it is superior to existing alternatives to centrifugation by validation with a ferritin lateral flow test. H.E.R.M.E.S is a suitable alternative for centrifugation in point-of-need settings and aims to facilitate the decentralization of commercial blood testing.

HERMES:在需要的地方快速分离血浆

全球医疗保健行业对免收CLIA的测试设施的需求不断增长,这些设施提供的诊断功能比传统实验室测试的成本更低,更方便。尽管出现了几种新的诊断工具来满足这些环境中的测试要求,但由于美国食品药品监督管理局(FDA)将离心机分类为最不适合在CLIA豁免的环境中使用,因此离心机已从过渡到需要的位置受到了阻碍。 。样品处理能力的局限性不利于免于CLIA的测试环境提供广泛的测试产品组合的能力,并且当今的诊断受到离心需求的瓶颈。在这里,我们介绍了高效快速磁性红细胞分离器(HERMES),一种快速,低成本的技术,可以用离心机的一小部分时间和成本执行从血浆中分离红细胞的工作。我们证明,HERMES能够在每次测试不到2分钟的时间内获得高纯度血浆(纯度大于99.9%)。此外,我们详细介绍了它是一种易于使用的方法,能够与当今的诊断技术结合使用,并通过铁蛋白横向流动试验的验证,证明它优于离心的现有替代方法。HERMES是在需要的地方进行离心分离的合适选择,其目的是促进商业血液检测的分散化。每次测试不到2分钟,S就能获得高纯度血浆(纯度大于99.9%)。此外,我们详细介绍了它是一种易于使用的方法,能够与当今的诊断技术结合使用,并且通过铁蛋白横向流动试验的验证,证明它优于离心法的现有替代方法。HERMES是在需要的地方进行离心分离的合适选择,其目的是促进商业血液检测的分散化。每次测试不到2分钟,S就能获得高纯度血浆(纯度大于99.9%)。此外,我们详细介绍了它是一种易于使用的方法,能够与当今的诊断技术结合使用,并通过铁蛋白横向流动试验的验证,证明它优于离心的现有替代方法。HERMES是在需要的地方进行离心分离的合适选择,其目的是促进商业血液检测的分散化。
