Laboratory testing plays an integral part in medical decision making. However, laboratory results can sometimes vary significantly, leading to anomalous outcomes that are not consistent with the clinical picture. These anomalies can occur even in the best of laboratories simply because the total testing process includes elements that are not totally under the laboratory's control. For example, variations in patient preparation and sample collection procedures, as can happen at physician offices or patients receiving intravenous fluids, are major contributors to these anomalies. Therefore, physicians must remain aware of the causes of these anomalies so they can consider them when interpreting laboratory results and help implement solutions to mitigate them at their respective institutions. This Core Curriculum examines several instances where an understanding of preanalytical, analytical, and postanalytical variation is essential for detecting anomalies and providing proper patient care.

基础代谢面板中的实验室异常：2025 年核心课程。


实验室检查在医疗决策中起着不可或缺的作用。然而，实验室结果有时可能会有很大差异，导致与临床情况不一致的异常结果。即使在最好的实验室中，这些异常也可能发生，这仅仅是因为整个测试过程包括不完全在实验室控制的元素。例如，患者准备和样本采集程序的变化（如在医生办公室或接受静脉输液的患者可能发生）是导致这些异常的主要原因。因此，医生必须始终了解这些异常的原因，以便他们在解释实验室结果时可以考虑这些异常，并帮助在各自的机构实施解决方案以减轻这些异常。本核心课程研究了几个实例，在这些实例中，了解分析前、分析和分析后变化对于检测异常和提供适当的患者护理至关重要。
