There have been numerous unsuccessful attempts to develop clinically useful serodiagnostic tests for tuberculosis. Although the large number of published reports clearly show that antibody levels are significantly higher in patients, as a group, than in a control population, little consideration is given to the value of the tests in various operational situations. In this paper we review the criteria generally used to assess the usefulness of a diagnostic test and introduce two new concepts--namely, operational predictive accuracy and operational acceptability.
为开发临床上有用的结核病血清学诊断测试,已经进行了无数次失败的尝试。尽管大量已发表的报告清楚地表明,总体而言,患者体内的抗体水平明显高于对照人群,但很少有人考虑这些测试在各种实际应用情况下的价值。在本文中,我们回顾了通常用于评估诊断测试有用性的标准,并引入了两个新概念,即操作预测准确性和操作可接受性。
