WS/T 229-2024《尿液理学、化学和有形成分检验》已于2024年5月正式发布，本次修订旨在适应近年来尿液检验技术的快速发展，解决实验室在实际操作、性能验证、质量控制和结果报告等方面存在的标准不统一、操作不规范等问题，从而进一步提升我国尿液常规检验的标准化水平和结果可比性。新标准的核心变化体现在术语定义的扩充、全过程质量管理的强化以及结果报告的规范化3个方面，并首次系统性地整合了“人员、设施和环境”的要求，引入了“性能验证”和“复检规则”等关键质量控制环节。本文将对新标准的主要内容尤其是更新后的内容进行详细解读，并结合国际国内相关标准、文献及实际工作场景，为临床实验室提供具体的应用指导与建议，以促进标准的有效实施，最终服务于临床诊疗的精准与高效。

The standard WS/T 229-2024 "Physical, chemical, and morphological examination of urine" was officially promulgated in May 2024. This revision aims to align with the rapid advancements in urinalysis technology in recent years, addressing prevalent issues in clinical laboratories such as inconsistent standards, non-standardized operations, and challenges in achieving result harmonization across practical procedures, performance verification, quality control, and reporting. Its objective is to further elevate the standardization and result comparability of routine urinalysis in China. The core updates of the new standard are manifested in 3 key areas: Expansion of terminology definitions, enhancement of total process quality management, and standardization of result reporting. Notably, it introduces, for the first time, a systematic integration of requirements for "personnel, facilities, and environment" and incorporates critical quality control components such as "performance verification" and "reflex testing rules". This article provides a detailed interpretation of the standard's main content, with particular focus on the revisions. Furthermore, it offers practical application guidance and recommendations for clinical laboratories, drawing upon relevant international and domestic standards, literature, and real-world scenarios. The ultimate goal is to facilitate effective implementation of the standard in support of accurate and efficient clinical diagnosis and treatment.
