In medical literature the value of diagnostic tests is most of the time appreciated from their statistical properties (sensitivity and specificity) and from the prevalence of a given disease. In this paper we also take into account economic parameters such as the benefits and costs of the potential treatment under consideration and we present a simple and flexible algebraic expression of the informative value of a test. In this way the informative content of a test can be easily evaluated and the quality of an existing test can be compared to that of a theoretically 'perfect' one. Two examples taken from the medical literature illustrate our approach.
在医学文献中，诊断测试的价值多数时候是从其统计学特性（敏感性和特异性）以及特定疾病的患病率来评估的。在本文中，我们还考虑了经济参数，例如所考虑的潜在治疗的收益和成本，并给出了一个关于测试信息价值的简单灵活的代数表达式。通过这种方式，可以轻松评估测试的信息含量，并将现有测试的质量与理论上“完美”的测试质量进行比较。从医学文献中选取的两个例子说明了我们的方法。
