对肺结核的诊断方法多年来未有改变，如痰涂片检查、痰培养以及胸片。极需有快速和准确的诊断结核的方法。晚近分子生物学的发展给应用新的方法诊断肺结核带来了希望。但大多数的方法集中在应用PCR技术对疑为分支杆菌感染的病人的疾标本进行诊断。本文作者应用前瞻性研究以评价 The diagnosis of tuberculosis has not changed over the years, such as sputum smear, sputum culture and chest radiographs. There is a great need for a quick and accurate method of diagnosing tuberculosis. Recent advances in molecular biology have given rise to new ways to diagnose tuberculosis. However, most methods focus on the use of PCR to diagnose diseased specimens of patients suspected of being Mycobacterium tuberculosis. The authors apply prospective studies to evaluate
