尿碘酸消化法测定中室内质控样的研制

Study on Internal Quality Samples by Urinary Iodine Chloric Acid Digestion

本文根据最近卫生部碘缺乏病专家咨询组提供的尿碘测定标准方法进行了尿碘室内质控样的制备，并对研制方法中有关问题进行了探讨。实验结果表明尿碘室内质控样基体代表性、均匀性、稳定性均好，准确度较高，既价廉又方便。尿碘实验室内质控样为尿碘测定分析质量保证体系提供了一个重要手段。

The chloric acid digestion method was used in the study on making urinary iodine internal quality samples. The result showed urinary iodine internal control samples was good in representative,homogeneity, stability and accuracy. The urinary iodine internal quality control samples provided an important method for quality assurance of urinary iodine analytical determination.
