Routine preoperative laboratory testing has become dogma to many. Often, surgeons, anesthesiologists, hospital administrators, and even patients expect that there will be some "labs" on the chart prior to any operative procedure. Many have questioned the usefulness and cost-effectiveness of such a policy. There is little evidence to support the need for routine preoperative testing and much evidence against it. Preoperative testing should be based on appropriate indications. This makes the assessment of the preoperative laboratory evaluation difficult for a medical quality assurance program. The question that arises is, how much routine preoperative laboratory testing is enough? The answer to this question depends on (a) the purpose of this testing and (b) the limitations and potential misinterpretations of laboratory testing. This article will discuss the reasons for the potential misinterpretation of laboratory tests and then the data supporting selective preoperative laboratory testing.
常规术前实验室检查对许多人来说已成为一种教条。通常，外科医生、麻醉师、医院管理人员甚至患者都期望在任何手术程序之前，病历上会有一些“检查报告”。许多人质疑这一政策的实用性和成本效益。几乎没有证据支持进行常规术前检查的必要性，而有很多证据反对这样做。术前检查应基于适当的指征。这使得医疗质量保证计划对术前实验室评估的评估变得困难。出现的问题是，多少常规术前实验室检查才足够？这个问题的答案取决于（a）这种检查的目的，以及（b）实验室检查的局限性和潜在的误解。本文将讨论实验室检查可能被误解的原因，然后讨论支持选择性术前实验室检查的数据。
