结核诊断指标在诊断肺结核中的临床意义

摘要

目的：探究结核诊断指标在诊断肺结核中的临床意义。方法选取160例肺结核患者和100例非结核患者，进行血结核抗体、PPD、胸部CT以及血沉阳性率的试验。结果在PPD硬结直径＞15 mm或＞20 mm时，PPD试验敏感性、特异性对比明显（P＜0.01）。而肺结核组中，患者胸部CT的阳性率高于血沉（P＜0.01）。结论 PPD试验对诊断肺结核起着重要的影响作用，胸部CT与PPD试验为最佳临床诊断方式。%Objective To explore the clinical signiifcance of tuberculosis diagnosis index in the diagnosis of pulmonary tuberculosis.Methods 160 patients with pulmonary tuberculosis patients and 100 cases of non tuberculosis patients. The serum tuberculosis antibody and PPD, CT of the thorax and the positive rate of erythrocyte sedimentation rate (ESR) test.Results In PPD induration diameter greater than 15 mm or greater than 20 mm, PPD test sensitivity and speciifcity of contrast (P<0.01). The pulmonary tuberculosis group, the positive rate of patients with chest CTwas signiifcantly higher than that of erythrocyte sedimentation rate (P<0.01). Conclusion PPD test plays an important role in the diagnosis of pulmonary tuberculosis. Chest CT and PPD test is the best method for clinical diagnosis.
