能够实现快速现场疾病诊断的低成本护理点(POC)设备可能会对全球健康产生重大影响,特别是如果它们能够提供指示疾病状态的分子(生物标记物)的定量测量。当有研究级、复杂的设备可用时,准确量化患者样本中的生物标记物已经是一项挑战;当限制在简单、成本效益高的POC平台上时,这一点更加困难。在这里,我们总结了准确、低成本POC生物标志物量化的主要挑战。我们还回顾了除了定性读数之外,最近开发和实施POC工具的努力,并确定了未来重要的研究方向。
Low-cost, point-of-care (POC) devices that allow fast, on-site disease diagnosis could have a major global health impact, particularly if they can provide quantitative measurement of molecules indicative of a diseased state (biomarkers). Accurate quantification of biomarkers in patient samples is already challenging when research-grade, sophisticated equipment is available; it is even more difficult when constrained to simple, cost-effective POC platforms. Here, we summarize the main challenges to accurate, low-cost POC biomarker quantification. We also review recent efforts to develop and implement POC tools beyond qualitative readouts, and we conclude by identifying important future research directions.
