摘要(Abstract)：

目的验证各实验室检测新生牛血清血红蛋白含量的能力。方法采用纤维蛋白原析出法制备验证样品,并采用单因素方差考察样品的均匀性,t检验考察稳定性。组织24家实验室采用《中国药典》三部(2015版)规定的方法对验证样品进行检测,以各实验室结果的中位值作为样品血红蛋白的指定值,标准化四分位距(normalised interquartile range,NIQR)作为变动性度量值(目标标准偏差),计算Z比分数(Z值)。结果验证样品具有良好的均匀性及稳定性。24家实验室中,2家退出,20家检测结果为"满意"(|z|≤2),2家为"不满意"(|z|≥3)。结论参加验证的实验室满意率总体达89.5%,未取得满意结果的实验室可通过分析问题,找出原因并采取相应的整改措施。
