While there is no generally applicable method of test reduction, ways in which the problem can be tackled can usually be suggested. These include the examination of error rates of tests and the use of current statistical methods. When the cost-effectiveness of some more expensive test has to be measured, a model of the decision problem needs to be developed, with an attempted estimation of the values or utilities of the states of health that result from treatment.
虽然没有普遍适用的减少检测的方法，但通常可以提出解决该问题的方法。这些方法包括检查检测的错误率以及使用当前的统计方法。当必须衡量某些更昂贵检测的成本效益时，需要建立一个决策问题模型，并尝试估计治疗所导致的健康状态的价值或效用。
