The laboratory analysis of samples can be a valuable adjunct to the investigation of outbreaks of disease and to the identification and correction of production inefficiency. However, the costs associated with laboratory analysis are high; consequently, a decision to involve laboratory analysis as part of an investigation should be made judiciously. The purpose for the sampling should be directed and, in general, restricted to tests whose results can lead to a management decision. When dealing with complex and difficult problems, there is a tendency to buy decision time by taking samples for laboratory testing with the philosophy of "let's see what the laboratory can come up with." Undirected sampling seldom yields results that can be interpreted meaningfully to resolve the problem at hand.
对样本进行实验室分析，对于疾病暴发调查以及识别和纠正生产效率低下问题而言，可能是一项很有价值的辅助手段。然而，与实验室分析相关的成本很高；因此，是否将实验室分析纳入调查的一部分，应谨慎做出决定。采样目的应明确，一般而言，应仅限于那些其结果能为管理决策提供依据的检测。在处理复杂棘手的问题时，人们往往会抱着“看看实验室能给出什么结果”的想法，通过采集样本进行实验室检测来争取决策时间。无目的的采样很少能得出可用于有意义地解读以解决手头问题的结果。
