Using information theory, a model communication channel has been constructed to assess the information gain from the performance of clinical chemical tests, in particular qualitative tests. The construct of the model communication channel is especially clear, and it can be easily adapted to the most varied clinical enquiries. The information theoretical parameters, transinformation and test capacity, are used to characterize the information properties of a clinical chemical test. The calculations necessary for the practical application can (primarily when matrices are used) be performed without difficulty, even by non-mathematicians, using modern table calculators. The procedure is illustrated with many numerical examples, and especially applied to combination of qualitative tests.
利用信息论构建了一个模型通信渠道，以评估临床化学检验（尤其是定性检验）的性能所带来的信息增益。该模型通信渠道的构建特别清晰，并且可以轻松适应各种不同的临床询问。信息理论参数——互信息和检验容量，用于表征临床化学检验的信息特性。实际应用所需的计算（主要是在使用矩阵时）即使由非数学家使用现代台式计算器也能毫无困难地进行。文中用许多数值示例说明了该程序，并特别应用于定性检验的组合。
