目的评价基于结核分支杆菌３８ＫＤａ等五种抗原的快速免疫色谱实验（澳大利亚ＩＣＴＴＢ）对可疑肺结核的临床诊断价值。方法以初诊可疑肺结核患者１２５例为受试对象，同时做痰涂片、培养，血清ＩＣＴＴＢ以及胸片检查。结果总的敏感性为４５％、特异性为１００％。结论此试验不能完全代替痰涂片抗酸染色检查，但二者联合使用，可使敏感性提高到６３６％ Objective To evaluate the clinical diagnostic value of suspected immunodeficiency syndrome (TB TB) based on the rapid immunochromatographic assay (ICT-TB) of five antigens such as Mycobacterium tuberculosis 38KDa. Methods Totally 125 patients with newly diagnosed pulmonary tuberculosis were selected as subjects and sputum smear, culture, serum ICTTB and chest X-ray examination. Results The overall sensitivity was 45% and the specificity was 100%. Conclusion This test can not completely replace the sputum smear acid-fast staining test, but the combination of the two can make the sensitivity increased to 63  6%
