Yunmiao Sun, Yingshu Zou, Chuanbao Zhang, Mingting Peng, Wenxiang Chen, Weiyan Zhou.

国家标准GB/T 44672-2024/ISO 21151:2020《体外诊断医疗器械 建立校准物和人体样品赋值计量学溯源性的国际一致化方案的要求》已于2024年9月29日发布,2025年4月1日起实施。该标准针对缺乏参考测量程序、适用有证参考物质或国际约定校准品的检验项目,提出由国际团体组织实施的一致化方案的要求,通过定义指定被测量最高水平的计量溯源性,以实现不同体外诊断医疗器械(IVD MD)检测结果的等效性。本文对该标准的核心内容进行解读,阐明一致化方案在提升检测结果可比性、推动结果互认中的应用价值。该标准解读有助于我国临床实验室与IVD制造商在实践中建立并完善一致化方案的溯源路径,为跨系统、跨平台的检测结果一致性与临床决策同质性奠定坚实基础。

GB/T 44672-2024/ISO 21151:2020 In vitro diagnostic medical devices-Requirements for international harmonisation protocols establishing metrological traceability of values assigned to calibrators and human samples, was released on September 29th, 2024 and came into effect on April 1st, 2025. This standard addresses the need for harmonisation protocols organized and implemented by international bodies in cases where reference measurement procedures, suitable certified reference materials, or internationally agreed calibrators are lacking. By defining the highest achievable level of metrological tracerability for a specified measurand, the standard aims to achieve equivalence of results from different in vitro diagnostic medical devices (IVD MD). This article interprets the core content of the standard and elucidates the value of harmonization schemes in enhancing the comparability of measurement results and promoting result interoperability. The interpretation of this standard will assist clinical laboratories and IVD manufacturers in China in establishing and improving traceability paths based on harmonization schemes in practice, thereby establishing a solid foundation for result consistency across different systems and platforms and homogeneity in clinical decision-making.
