结核病临床诊断中，常采用痰涂片、抗酸杆菌染色和结核菌培养等方法。由于涂片法敏感性低，而培养法阳性率虽高但操作复杂，需要时间较长，不利于结核病的诊断[1]。一般认为酶联法检测抗结核抗体仍不失为结核病，特别是肺外结核诊断中有价值的实验室辅助检查之一。应用酶联免疫
Tuberculosis clinical diagnosis, often using sputum smear, acid-fast bacilli stain and TB culture and other methods. Due to the low sensitivity smear method, while the culture method, although the positive rate is high but the complexity of the operation, takes a long time, is not conducive to the diagnosis of tuberculosis [1]. It is generally believed that the enzyme-linked immunosorbent assay for detecting anti-TB antibodies is still regarded as one of the valuable laboratory auxiliary tests for the diagnosis of extra-pulmonary tuberculosis. Application of enzyme-linked immunosorbent
