Modern laboratories offer cost-effective and precise analysis of specimens. Unfortunately, accurate laboratory tests still can result in bad outcomes because of errors in the pre- and postanalytic phases of testing. Important sources of error in the preanalytic phase include errors in test ordering, patient identification, specimen collection, transport, and accessioning. Errors in the postanalytic phase often relate to turn-around time, delivery of reports, or interpretation of results. This article focuses on the key opportunities for improvement in quality.
现代实验室能够提供经济高效且精确的样本分析。不幸的是，由于检测前分析阶段和后分析阶段的误差，准确的实验室检测仍可能导致不良结果。分析前阶段的重要误差来源包括检测医嘱、患者识别、样本采集、运输和登记方面的错误。分析后阶段的误差通常与周转时间、报告交付或结果解读有关。本文重点关注质量改进的关键机会。
