A diagnostic examination may be called rational if it leads to a short, less costly and especially more certain diagnosis for the patient. Among other things, sensitivity and specificity, i.e. the proportion of correct positive to correct negative results of the separates steps of the examination determine the reliability of the answers to diagnostic questions. In most hypertensive patients the diagnosis can be completed in medical general practise. First results in West Germany show that only about 5 to 10% of patients require further investigations in special practices, general hospitals or special departments.
如果一项诊断检查能为患者带来简短、成本较低且尤其更准确的诊断，那么它就可以被称为合理的。除其他因素外，敏感性和特异性，即检查各个步骤中正确阳性结果与正确阴性结果的比例，决定了对诊断问题答案的可靠性。在大多数高血压患者中，诊断可在普通医疗实践中完成。西德的初步结果表明，只有约5%至10%的患者需要在专科诊所、综合医院或专科科室进行进一步检查。
