This 1992 Clinical Chemistry Forum asks if accuracy and precision goals for the laboratory can be specified by reference to medical requirements, which are a function of the total laboratory testing process as well as the needs of patients, clinicians, and societal institutions. Furthermore, medical decisions and decisions about medical requirements must be made in situations of uncertainty and thus are subject to predictable cognitive errors. The interaction of all these factors must be considered by patients, laboratorians, and clinicians to identify practical and effective performance goals. Pathologists and clinical chemists are uniquely trained to identify thoughtful clinicians who are knowledgeable in quantitative judgment to participate in this goal-setting endeavor. It is time for these parties to accumulate the available data and engage in the synthesis of effective performance goals.
1992年的这次临床化学论坛提出，实验室的准确性和精密度目标是否可以参照医学要求来确定，而医学要求是整个实验室检测过程以及患者、临床医生和社会机构需求的函数。此外，医学决策以及关于医学要求的决策必须在不确定的情况下做出，因此容易出现可预测的认知错误。患者、检验人员和临床医生必须考虑所有这些因素的相互作用，以确定切实可行且有效的性能目标。病理学家和临床化学家经过专门培训，能够识别出在定量判断方面知识渊博、深思熟虑的临床医生，让他们参与到这一目标设定工作中来。现在是这些相关方积累现有数据并参与制定有效性能目标的时候了。
