必须从病人的分泌物或组织中培养出结核分支杆菌,并有相应的临床表现,才能诊断结核病。一但疑有结核则应采取一系列诊断步骤,如X片、结核菌素皮试、支气管镜检查以及其他组织针刺活检等;最终还有小部分病人虽无细菌学及组织学阳性资料,但根据流行病学资料分析、系列X片及其对化疗反应等也可以作出正确诊断。 Mycobacterium tuberculosis must be cultured from the patient’s secretions or tissues and have the appropriate clinical manifestation to diagnose tuberculosis. Once suspected of tuberculosis should be taken a series of diagnostic steps, such as X-ray, tuberculin skin test, bronchoscopy and other tissue acupuncture biopsy; eventually there is a small number of patients without bacteriological and histological positive data, However, according to epidemiological analysis, a series of X-ray and its response to chemotherapy can also make the correct diagnosis.
