现阶段临床诊断结核分枝杆菌感染的常用检查方法包括旧结核菌素(OT)试验、痰找结核分枝杆菌等,前者阳性率低需反复筛查,后者检测指标国人与欧美国家差异很大。对此,本文主要解析痰找结核分枝杆菌需反复进行检查的原理,OT试验对我国和欧美国家患者诊断意义的差别,并说明诊断指标的高患病率和高特异性可增加诊断的阳性预测值,高敏感性可增加诊断的阴性预测值。提示医师应熟知诊断指标的应用原理,将其合理应用于临床实践,以利于更好地作出临床诊断。
At this stage of clinical diagnosis of Mycobacterium tuberculosis commonly used test methods include the old tuberculin (OT) test, sputum to find Mycobacterium tuberculosis, the former low positive rate to be repeated screening, the latter test indicators of people and Europe and the United States is very different Big. In this regard, this paper mainly to find the principle of sputum to find Mycobacterium tuberculosis to be repeatedly checked, OT test on the significance of the diagnosis of patients in China and Europe and the United States the difference, and that the diagnostic indicators of high prevalence and high specificity can increase the positive diagnosis Predictors, hypersensitivity can increase the negative predictive value of the diagnosis. Prompt physicians should be familiar with the application of diagnostic criteria, its rational application in clinical practice, in order to facilitate better clinical diagnosis.
