为了评估三种血清学快速检测方法对肺外结核和结核感染的诊断价值。方法：用结明试验，一步法和ＩＣＴ－ＴＢ卡检测了６８例肺外结核和２０例结核感染者血清抗结核抗体，并与肺结核组，非结核对照组和正常对照组做比较。结果：结核感染组结明试验，一步法检测和ＩＣＴ－ＴＢ卡诊断阳性率分别为７０％、６０％和２０％，肺外结核组诊断阳性率分别为８３．８％、７６．４％和５２．９％。三种方法联合检测总阳性率达９６．５％，对照组假阳性率为６．３％。结论：三种血清学检测方法简单、实用、快速、重复性好。联合应用对肺外结核和结核感染有重要辅助诊断价值，值得临床推广应用。
In order to evaluate the diagnostic value of three serological rapid tests for extrapulmonary tuberculosis and tuberculosis infection. Methods: The serum anti-tuberculosis antibodies of 68 cases of extrapulmonary tuberculosis and 20 cases of tuberculosis infection were detected by the knot-test, one-step method and ICT-TB card, and compared with tuberculosis group, non-tuberculosis control group and normal control group. Results: The positive rate of tuberculosis infection was 70%, 60% and 20% in tuberculosis test, one-step test and ICT-TB card respectively. The positive rate of tuberculosis in tuberculosis was 83.8% and 76.4% respectively 52.9%. The total positive rate of the three methods combined detection was 96.5%, the false positive rate of the control group was 6.3%. Conclusion: The three serological detection methods are simple, practical, rapid and reproducible. Joint application of extra-pulmonary tuberculosis and tuberculosis have important diagnostic value, is worthy of clinical application.
