To address the role of proficiency testing in the medical usefulness of laboratory tests, nine steps involved in the generation and application of a laboratory test result are identified and discussed: test ordering, patient preparation, specimen, sample, analysis, result, reporting, recognition, and action. Clinical uses of test results are enumerated. Good clinical skills are necessary for optimal test efficiency. Clinicians should improve their selection of tests, pay attention to proper patient preparation, and refine the process of interpretation of test results using disease-based reference ranges and more formal analysis of predictive value. By better definition of the clinical uses of laboratory tests, appropriate attention can be directed to steps in the laboratory domain such as medically relevant goals for accuracy and precision. With clearer understanding of the testing process, proficiency testing for monitoring laboratory performance can be more fully utilized. Audit models should be developed that include assessment of the outcome of the laboratory testing process.
为探讨能力验证在实验室检测医学实用性中的作用，本文确定并讨论了实验室检测结果产生及应用所涉及的九个步骤：检测医嘱、患者准备、标本、样本、分析、结果、报告、识别及行动。列举了检测结果的临床用途。良好的临床技能对于实现最佳检测效率至关重要。临床医生应改进检测项目的选择，注重患者的适当准备，并利用基于疾病的参考范围和更正式的预测值分析来完善检测结果的解读过程。通过更明确地界定实验室检测的临床用途，可以将适当的注意力导向实验室领域的各个步骤，如医学上相关的准确性和精密度目标。随着对检测过程的更清晰理解，可更充分地利用能力验证来监测实验室性能。应开发包括对实验室检测过程结果评估的审核模型。
