In this Perspective, we present evidence that indicates a discrepancy between laboratory and field performance of point of use water treatment (POUWT) techniques, identified via a narrative review process to investigate the origin of the LRV comparison estimates reported by the WHO. We considered only peer-reviewed articles that reported laboratory and field log reduction values (LRVs) for the same POU technology. We will present a summary of explanations that have been offered by the literature regarding such discrepancies; the potential implications of the “laboratory versus field” data discrepancy; and potential risks posed by conflating the two. Finally, in view of this discussion, we propose a strategy to help mitigate the research gap and explore the potential to improve current health risk assessments and ultimately, recommendations by public health entities and manufacturers of POUWT products.

在此观点中，我们提供证据表明使用点水处理 (POUWT) 技术的实验室和现场性能之间存在差异，这是通过叙述性审查过程确定的，以调查 WHO 报告的 LRV 比较估计的来源。我们只考虑了同行评审的文章，这些文章报告了相同 POU 技术的实验室和现场对数减少值 (LRV)。我们将总结文献中关于此类差异的解释；“实验室与现场”数据差异的潜在影响；以及将两者混为一谈所带来的潜在风险。最后，鉴于此次讨论，我们提出了一项战略，以帮助缩小研究差距并探索改善当前健康风险评估的潜力，并最终，
