Present status and problems in external quality control of immunoassays were described. Despite the increasing popularity of these methods, there are many difficulties in achieving good analytical performance. Consequently, immunoassay results demonstrate poor interlaboratory comparability. To exclude these difficulties, several changes should be made, for example, preparation of common reference standards, consent methods to give values to laboratory working standards, reference methods, matrix of test samples similar to actual clinical samples etc, before constructing suitable external quality control systems.
描述了免疫分析外部质量控制的现状和问题。尽管这些方法越来越受欢迎，但要实现良好的分析性能仍存在许多困难。因此，免疫分析结果显示实验室间可比性较差。为排除这些困难，在构建合适的外部质量控制体系之前，应进行一些改变，例如，制备通用参考标准品、赋予实验室工作标准品值的统一方法、参考方法、与实际临床样本相似的测试样本基质等。
