用改良ＥＬＩＳＡ法检测４５例肺结核，３８例非结核性肺部疾病（其中肺炎２０例，肺癌１８例）和３０例健康献血员血清中抗结核抗体。结果：肺结核组阳性率达９３．３％。肺结核组ＯＤ值为０．９２±０．１１，明显高于健康献血员组ＯＤ值０．３７±０．２２，两者差异非常显著（Ｐ＜０．００１）。非结核的肺炎组ＯＤ值为０．４７±０．１０，肺癌组ＯＤ值为０．４９±０．１０。肺结核组与肺炎、肺癌组相比差异亦非常显著（Ｐ＜０．００１）。提示，此法的检测对肺结核诊断具有临床意义。
45 cases of pulmonary tuberculosis, 38 cases of non-tuberculous pulmonary diseases (including 20 cases of pneumonia, 18 cases of lung cancer) and 30 healthy blood donors were detected by modified ELISA. Results: The positive rate of pulmonary tuberculosis was 93.3%. The OD of tuberculosis group was 0.92 ± 0.11, which was significantly higher than that of healthy blood donors (0.37 ± 0.22) (P <0.001). The OD of non-tuberculosis pneumonia group was 0.47 ± 0.10, and that of lung cancer group was 0.49 ± 0.10. The difference between tuberculosis group and pneumonia group and lung cancer group was also significant (P <0.001). Tip, this method of detection of pulmonary tuberculosis has clinical significance.
